Visit to Seoul, South Korea
During my recent visit to South Korea, I had the privilege of meeting various stakeholders, including representatives of government, research institutions, and academia, to understand their needs and communicate MDPI’s commitment to accessible science. Accompanied by my colleagues Dr. Giulia Stefenelli and Dr. Jisuk Kang, I engaged with the Korean scientific community, which is increasingly embracing open access (OA).
As the leading OA publisher in South Korea, MDPI is trusted by local authors and in 2023 enjoyed an approximately 30% share of the OA market. South Korea ranks sixth globally for MDPI in terms of research papers submitted and published.
MDPI and South Korea by Numbers
As at 30 March, over 76,000 MDPI articles have been authored by individuals affiliated with Korean institutions. We have over 1,800 active editorial board members (EBMs) from South Korea, with more than 880 EBMs having an H-index between 26 and 50, including 10 serving as Chief Editors.
“South Korea is the sixth-largest contributor to our total publications”
Over the past five years (2019–2023), nearly 120,000 authors affiliated with South Korean institutes have published with MDPI. Specifically in 2023, we received approximately 25,000 submissions from South Korean authors, publishing close to 13,000 articles, resulting in a rejection rate of 47.4%, which is not far below MDPI’s overall rejection rate of 56.4% in 2023.
Institutional Partnerships with South Korea
I am pleased to share that MDPI has more than 825 institutional partnerships worldwide, with 12 in South Korea, including Kyunghee University, Chung-Ang University, and Inha University, among others.

Coming Together for Science
MDPI Joins United2Act in Collective Fight to Stop Paper Mills
In my February 2024 CEO Letter, I highlighted some of our recent initiatives aimed at bolstering our commitment to research integrity, including joining the STM Integrity Hub and expanding our Research Integrity and Publication Ethics team (RIPE). Continuing our efforts in coming together for science, I am pleased to share our participation in the United2Act initiative.
The text below is taken from our official announcement:
United2Act represents an international group of stakeholders in the publishing industry committed to addressing the collective challenge posed to research integrity by paper mills.
Scientists and academic publishers have increasingly noted the alarming proliferation of paper mills, recognized as fraudulent entities seeking to manipulate the publication process for financial profit. These entities engage in fraudulent practices such as falsifying or fabricating data, selling co-authorship of fake papers, manipulating peer review, and including inappropriate citations. These actions pose a significant threat to the integrity of the scholarly record, prompting widespread concern among those involved in the academic community.
MDPI has been actively contributing to combat the undermining of the scientific record. Our editors employ a set of tools to detect potential ethical breaches within a manuscript and to tackle the issue of fake papers.
United2Act’s consensus statement is the outcome of a virtual summit held in May 2023. It involved the participation of research bodies, publishers, researchers/sleuths, universities, and publishing infrastructure from 15 countries and resulted in a Consensus Statement outlining five key areas of action for all stakeholders:
- Education and awareness
- Improve post-publication corrections
- Facilitate and organise research on paper mills
- Enable the development of trust markers
- Facilitate dialogue between stakeholders
MDPI is committed to promoting transparency and integrity in scholarly publishing and is continuing to work closely with the scientific community toward this goal.

Visit to Tokyo and Kyoto, Japan
In March, I had the opportunity to visit our Tokyo office and engage with stakeholders in Tokyo and Kyoto. During the visit, I also recorded a video message to welcome Japanese scholars working with MDPI and to highlight our operations in Japan.
We held meetings with Editors-in-Chief, librarians, scholars, and external consultants to gather feedback on our efforts to enhance our reputation and explore additional steps we can take in that direction. Japan's rich cultural heritage, characterized by tradition, respect, and formality, provided valuable insights into meeting the publishing needs specific to Japan.
Japan’s Open Access statistics
Over the years, we have seen a shift from subscription-only to gold OA publishing in Japan, despite the lack of an official mandate. Here are some statistics:
- 2012: 68% of articles were subscription-only, 6% were green Open Access, and 8% were gold Open Access.
- 2016: 55% of articles were subscription-only, 6% were green Open Access, and 20% were gold Open Access.
- 2022: 43% of articles were subscription-only, 7% were green Open Access, and 39% were gold Open Access.

MDPI and Japan by Numbers
As at 1 April, over 50,000 MDPI articles have been authored by scholars affiliated with Japanese institutions, making the country the ninth-largest contributor to our total publications. Over the past three years (2020–2023), nearly 90,000 authors affiliated with Japanese institutes have published with MDPI, and we have collaborated with over 4,600 Guest Editors from Japan.
In 2023, we published over 8,200 papers from authors associated with Japanese institutions. MDPI collaborates with 41 institutional partnerships in Japan, including the University of Tokyo, Hokkaido University, and Nagoya University. We have over 2,100 active EBMs from Japan, more than 1,050 EBMs having an H-index between 26 and 50, including 13 serving as Editors-in-Chief.
General Feedback – a side note
A general takeaway from our discussions with stakeholders from around the world is that negative perceptions of MDPI often stem from misinformation, misconceptions, or misunderstandings about MDPI and our practices. While we acknowledge our mistakes and work diligently to address them, maintaining a strong editorial procedure and robust peer-review process, I find that educating stakeholders about our how we do what we do and our ongoing improvements tends to help shift opinions.
That said, we recognize the importance of addressing individual concerns. We take feedback seriously and are continuously working to get better while not compromising the core principles that millions of authors appreciate about MDPI.

Closing Thoughts
Researcher to Reader (R2R) Conference
From 20–21 February 2024, I had the pleasure of attending the Researcher to Reader (R2R) conference in London, which MDPI has proudly sponsored over the years. The conference programme offered a variety of session formats, including workshops, panel discussions, debates, interviews, presentations, and lightning talks, with opportunities to discuss relevant topics.
We take pride in supporting the scientific community, bringing researchers across the world together to network, exchange ideas and share the latest in science and publishing. In 2023, MDPI invested close to 2 million CHF in sponsoring over 2,000 scientific and publishing-related conferences worldwide.
R2R Peer Review Innovations Workshop
I found the R2R conference to be engaging, with the workshops being particularly enjoyable. My colleague Giulia Stefenelli (Chair of Scientific Office Board) and I participated in the “Peer Review Innovations” workshop, which spanned four sessions over the two days. These sessions explored the future of peer review and how we can improve the peer review process for everyone involved. Notably, the large majority of attendees expressed their opinion that peer review, as currently practiced, requires significant improvement. Together, we collaborated on potential immediate and long-term improvements and innovative processes, aiming to create an ecosystem beneficial to all stakeholders by strengthening submission systems with the aim of reducing threats and making authors more responsible for their work. We also discussed the opportunity for academic institutions to better scrutinize the quality of the work produced and submitted to journals.
Our group comprised publishers, software providers, librarians, and more, bringing diverse perspectives to the discussions. These interactions were relevant to MDPI’s ongoing conversations, providing insights to our efforts. The session also made me appreciate that MDPI is doing well, as the group discussions included the subject of various quality checks that we have already embedded in our processes, ensuring that we keep abreast of industry standards.
The need for an optimized system to incentivize the activities of editors and reviewers was also a focus of discussion, as well as the support that reviewers need from publishers via the provision of strong reports through fixed forms, questionnaires and training.
At MDPI, we are currently auditing our reviewer program to improve reviewer recognition, guidelines, and methods for identifying suitable reviewers, while maintaining our commitment to quality and timeliness.
Congratulations to Mark Carden, Conference Director, and the R2R team for organizing a productive and successful event. PS: The break times were greatly appreciated as well!

During our meeting, we discussed MDPI’s publishing philosophy and explored further avenues for collaboration. We look forward to continuing our partnership with Digital Science, aiming to improve our services yet further and meet the needs of our authors more closely than ever.
What is Altmetric?
You will notice that MDPI articles feature an Altmetric score, a colourful doughnut capturing the score in the upper right corner of the article page. This score represents ‘alternative metrics,’ as distinct from traditional metrics such as Impact Factor, CiteScore, and Scimago Journal Rank.
Altmetrics complement traditional citation-based metrics by capturing online discussions related to a specific research topic. By analyzing both sets of data, we can obtain a comprehensive understanding of the attention a particular research output receives and the sources in which it is mentioned.
“Almetric provides visual insights into where research is being discussed”
Sources Tracked by Altmetric
Altmetric badge showing the Altmetric score and colour-coded mention sources.
Altmetric monitors various sources, categorizing them into segments such as policy documents, peer reviews, Wikipedia, news and blogs, and social media, among other sources. Each category is identifiable by a specific colour.
The Altmetric badge provides visual insights into where the research is being discussed. A more colourful badge indicates broader mentions across multiple platforms. Such tracking enables us to gauge the extent of an article’s online dissemination, noting that increased visibility may correlate with higher citation rates.

MDPI Annual Meeting Celebrations in China
On Thursday 25 January, over 1,300 MDPI colleagues from our two offices in Beijing gathered to kick off MDPI’s traditional ‘Annual Meetings.’ These celebrations take place in MDPI’s offices across China, including Dalian, Tianjin, Wuhan, and Nanjing.
The evenings include performances, informative talks and presentations, awards, and entertainment, providing an ideal platform to recognize our colleagues, celebrate their achievements, and set our sights on the future.
“It is essential that we stay connected and share best practices”
I sent a video congratulating everyone on their work and sharing our vision of building MDPI into the most trusted OA publisher, highlighting the roles each of us has to play in achieving that goal.
Unfortunately I could not join in person, but you may recall my recent trip, when I visited our offices in Beijing and Wuhan, which I look forward to visiting again this year.
Although our headquarters are in Basel, Switzerland, and we are expanding throughout Europe and North America, the majority of MDPI’s workforce is in China and throughout the Asia-Pacific region, including offices in Singapore, Thailand, Japan, and newly opened office in South Korea. It is essential that as a global organization, we stay connected and share best practices in order to grow collectively and continue providing the exceptional service to our authors.
The Annual Meeting is a moment to reflect and enjoy the year’s hard work and dedication.
I extend our best wishes to all for the Chinese New Year (Xīnnián kuàilè)!

Closing Thoughts
Reflections on the 2024 APE Conference
MDPI was proud to co-sponsor the Academic Publishing in Europe (APE) 2024 Conference that took place in Berlin, Germany, from 9–10 January 2024.
The conference theme, ‘Keep the Conversation Going!’, explored the evolving landscape of scholarly communication. APE is one of the key conferences I make a point to attend each year. January offers a valuable opportunity to engage with new contacts, reconnect with familiar faces, and participate in impactful discussions and presentations among professionals, scholars, and practitioners in the field.
“It's fascinating to see how other publishers are leveraging AI”
Highlights
Some of the standout panels for me include: the role of the UN Sustainable Development Goals (SDGs) within the publishing industry. It was encouraging to hear the current status quo, though I was eager also to learn about the exciting projects planned for 2024 and beyond. These will allow us to track progress in subsequent years. At MDPI, we remain committed to promoting Open–Access (OA) content on SDGs through scientific articles and books. Furthermore, we extend our commitment to sustainability by financially supporting researchers through initiatives such as the World Sustainability Award and the Emerging Sustainability Leader Award, as well as waiving the APC for feature papers on each SDG.
In recent years, discussions on AI have become increasingly prominent at such conferences. It’s fascinating to see how other publishers are leveraging AI to meet the evolving needs of their audiences while at the same time using it to safeguard the scientific process. Other engaging panels that I enjoyed included updates on transformation beyond transformative agreements, the principles of lean change, incentive structures related to research integrity, and the panel on reviewer incentives.
“We can share best practices and lessons learned”
Incorporating MDPI’s Insights into Conferences
I must confess that I sometimes feel overlooked when MDPI is not invited to participate in crucial industry discussions. As the leading open access publisher and the third-largest publisher overall, we possess extensive experience in many of these areas and can offer valuable contributions to these discussions. We can share best practices, lessons learned, and our thinking about future trajectories. For instance, in panels discussing reviewer incentives, at MDPI we offer a discount voucher to reviewers for future submissions, reflecting our commitment to fostering a robust peer review process. In 2022 alone, MDPI collected over 1.4 million peer review reports, informing the decision-making processes of our editors. Given our expertise in these areas, it would be natural to include MDPI in such discussions. I therefore extend an invitation to future conference organizers to consider MDPI for speaking engagements and collaborative opportunities.

MDPI Journals Newly Indexed in 2023
The aim of indexing is to enhance the quality and credibility of published research, ensuring that researchers access the most credible resources available. While the principle behind citation indexing is straightforward, it remains one of the most dependable methods for tracking an idea's evolution across various scientific disciplines.
Throughout the year, MDPI works to expand the reach of our publications across premier multidisciplinary databases like Web of Science, Scopus, EBSCO, and ProQuest. This initiative is spearheaded by MDPI's Indexing team, under the leadership of Dr. Constanze Schelhorn.
In 2023, MDPI achieved 54 new acceptances in Scopus, 29 in Web of Science, 52 in EBSCO, and 83 in DOAJ: Directory of Open Access Journals.
The team prioritizes ensuring that our journals feature in numerous specialized databases, including PMC, PubMed, MEDLINE, Inspec, CAS, and FSTA, among others. Currently, MDPI collaborates with over 65 renowned international databases, consistently enhancing our database affiliations annually.
MDPI’s journals are indexed in all major global databases.
Furthermore, we collaborate with universities and government organizations to list our journals in country-specific ranking lists and relevant institutional repositories. This ensures compliance with requirements often set by funders or institutions for authors to publish in specific journals.
Web of Science Adds 24 MDPI Journals to Emerging Sources Citation Index (ESCI)
Clarivate recently analysed MDPI’s new journals, resulting in 24 journals, mainly established in 2020, being added to the ESCI in November and December 2023. Additionally, five journals passed this assessment earlier in the year. For a complete list of our journals in Web of Science, refer here. Journals in the ESCI meet 24 quality criteria, ensuring editorial rigor. They may be considered for inclusion in broader indices like the Science Citation Index Expanded (SCIE), the Social Sciences Citation Index (SSCI), or the Arts and Humanities Citation Index (AHCI), based on four impact criteria.

Reflecting on 2023 and Looking Ahead to 2024
As we approach 2024, I reflect on the incredible journey we’ve had together at MDPI this year. The past 12 months have been marked by ambitious projects and initiatives to improve our internal processes, and a commitment to continue delivering top-notch services to our stakeholders. I’d like to thank each and every one of our staff members for contributing to the positive experiences our stakeholders have reported in our surveys. Your dedication to speed, efficiency, and effective communication with our stakeholders is very much recognized and appreciated.
Becoming a stronger organisation
While we have encountered challenges in 2023, it’s important to understand that these are a part of our growth process. Difficulties provide us with opportunities to reflect, address problems at their roots, and ultimately evolve into a stronger organization. Our stakeholders expect us to overcome tough times, and it’s an expectation that we have for ourselves.
I extend my sincere appreciation to every MDPI employee, from our editorial office and IT department to marketing, indexing, IOAP, societies, Scientific Office board, products, production, conferences, finance, operations, admin, and beyond. To our newest team members, a warm welcome; to our longstanding colleagues, your dedication is invaluable.
“I am committed to taking MDPI to a new level of excellence.”
Interacting with many of you during my visits to our offices and representing MDPI at external events has been a personal highlight. I am deeply grateful to Dr. Lin for entrusting me with the role of CEO of MDPI. Looking forward, I am committed to working closely with our management team to lead MDPI and take it to a new level of excellence, aiming to establish it as the most trusted publisher in open access worldwide. This is a collective endeavour, with each of us shaping MDPI’s reputation. I therefore encourage us to take pride in our work, as it represents not only our craft but also MDPI as a whole.
Accountability and communication
As we look forward to 2024, there’s a lot to be excited about. Together, we’ll navigate challenges, seize growth opportunities, and refine our practices. To solidify MDPI’s position as the premier open access publisher globally, we must bolster accountability, improve stakeholder communication, share MDPI’s best practices, champion the open access philosophy, and educate stakeholders about our mission, methodologies, and motivations.
Thank you for engaging with the CEO Letter over the past six months of 2023. I will continue to release this newsletter as a method of sharing the great work being done at MDPI. Please feel free to connect directly with any insights or questions.

MDPI Insights: The CEO’s Letter #6 - MDPI Spain Summit and ResearchGate
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
MDPI Spain Summit
Stefan Tochev (CEO, MDPI) gives the opening speech at the MDPI Spain Summit.
On Friday 10 November 2023 I was in Barcelona, Spain, to deliver the opening presentation and participate in a panel at MDPI’s Spain Summit, a two-day event, inspired by our salon events in China.
With 16 Editors-in-Chief (EiCs) and 20 Editorial Board Members (EBMs) in attendance, the event, organized by our conference team and Barcelona office, featured presentations on open access (OA), MDPI, and publishing market trends in Spain.
The event provided a great opportunity to engage with stakeholders from various MDPI journals, including Nutrients, Vaccines, Buildings, IJMS, and others. We were able to gather feedback and have open conversations around manuscript quality, the peer-review process, and journal development, as well as accreditation agencies.
Connecting with Editorial Board Members
Stefan Tochev in conversation with Summit participants: "Our EBMs are passionate about the journals they serve."
Interacting with our EBMs in person provides a valuable opportunity to show how important it is to us to connect with them, hear their perspectives on their journals and learn more about their own experience collaborating with MDPI.
From my conversations, it was clear that our EBMs are passionate about the journals they serve. I know the advice they provide may sometimes involve just small tweaks, but these can lead to important improvements. As the saying goes, small hinges swing open big doors.
As at November 2023, MDPI has over 6,300 EBMs affiliated with Spanish institutions, with more than 30 of them serving as EiCs or section EiCs. Furthermore, over 68,000 Spanish scholars have contributed as reviewers in MDPI journals.
Open Access in Spain
In 2023, Spain implemented legislation mandating immediate OA for all publicly funded research, aligning with the EU’s Plan S initiative to expedite the transition to OA. The Spanish government also approved a four-year, €23.8 million annual budget for the first national OA strategy, aiming to make publicly funded research freely accessible upon publication. This strategy aims to strengthen the quality and transparency of research in Spain, and to help promote movement towards a digital, low-carbon economy.
For further details of Spain's OA policy and the history of government mandates, click here.
Spain has already seen a notable decline in subscription-only articles, decreasing by 62% over a 10-year period, while gold OA increased by 42%. Green OA slightly decreased, suggesting a shift towards publishing in gold OA journals rather than traditional subscription-based ones. Here are some statistics from Scopus.
A big thank-you to the various MDPI teams, including our conference team and the Barcelona office, for organizing this very successful event!
MDPI colleagues from various offices gathered to host and support the first MDPI Spain Summit, in Barcelona, Spain.
I think this type of gathering has the potential to become an annual event in various locations. For example, Manchester could be an option, as we have over 30 EiCs and over 3,000 EBMs in the UK, a top market for MDPI that publishes high-quality research.

Corporate Marketing and Communications Strategy Session
Members of MDPI’s Corporate Marketing & Communications team.
For the past few years, I have led the Corporate Marketing & Communications department in our annual strategy session.
This typically involves 2–3 days of focused sessions covering key topics including budgeting, hiring targets, campaign reviews, and planning for the upcoming year, department strategy, and structure.
We are constantly exploring ways to optimize the Corporate Marketing & Communications department to support MDPI’s primary objectives and better convey the MDPI story while serving the scholarly community.

ResearchGate and MDPI Partner to Boost the Visibility of Open Access Content through Journal Home
Stefan Tochev (CEO, MDPI) and Sören Hofmayer (Co-Founder and Chief Strategy Officer, ResearchGate) meet in Berlin, Germany to take their ongoing discussion further.
When I assumed the role of CEO at MDPI, my primary focus was to initiate the building of essential partnerships and collaborations within our industry. After all, I am a firm believer in achieving our goals by helping others achieve theirs and focusing on co-opetition wherever there is an opportunity. I first touched on the notion of co-opetition in MDPI Insights: The CEO's Letter #3, particularly when discussing collaborations with Elsevier.
In light of this, Sören Hofmayer (Co-Founder and Chief Strategy Officer at ResearchGate) and I connected recently to continue a discussion that had been ongoing for months. I was quickly brought up to speed and felt there was an opportunity for MDPI journals to pilot the Journal Home service that ResearchGate had launched. This would provide a new way for MDPI to engage with authors and readers and amplify the visibility of our journals.
While I receive many offers and opportunities for discussions with vendors, I am a firm believer that timing is everything, and in this case, the time for us is now. Sören and I met in person during my recent visit to Berlin and decided to proceed with piloting ten MDPI journals with the Journal Home service.
The press release below provides further details.
Press Release: Berlin (Germany) and Basel (Switzerland), 15 November 2023
ResearchGate, the professional network for researchers, and MDPI, the largest open access publisher in the world and a pioneer in open access publishing, today announced a partnership that will see ten of MDPI’s open access journals benefit from an enhanced presence on ResearchGate through its innovative Journal Home offering.
This new partnership will expand the reach and visibility of MDPI’s participating flagship journals with ResearchGate’s highly relevant community of more than 25 million researchers globally.
Around 210,000 version-of-record articles from these 10 titles will be readily available on ResearchGate, including the full archive material and all new articles as they are published. These journals also benefit from enhanced brand visibility, with dedicated journal profiles, prominent representation on all associated article pages and all relevant touchpoints across the ResearchGate network – keeping the journals top-of-mind with their reader and author audiences. All articles covered by the new partnership will automatically be added to the authors’ publication records in ResearchGate. This not only reduces MDPI authors’ needs for direct management but also offers them valuable insights into the impact of their work, including data about readership and citations.
Closing Thoughts
November is Men’s Health Awareness Month
Stefan Tochev (CEO, MDPI) listening to music as he writes at a coffee shop in Basel, Switzerland.
November is dedicated to raising awareness of various men’s health issues. I have been fortunate to have positive male role models in my life, and I strive to share my experiences with others.
I used to take part in Movember, growing my moustache throughout November to raise awareness and funds and to help “change the face of men’s health.” With male family and friends impacted by physical and mental health issues, I have recently become more interested in men’s overall well-being.
Men often face stigma involving the perceived need always to be strong and have things figured out. Recently, I’ve had meaningful conversations with male friends and colleagues about issues we rarely discuss, and it was a positive experience.
Various factors impact men’s health and well-being, all too easily leading to risky health behaviours including a lack of health awareness, poor health education, and negative, culturally induced, behaviour patterns in our work and personal lives. I hope we can break down these barriers in our work environment.
Healthy men help build healthy families and a healthy society
Men are less likely than women to seek help with their physical and mental health struggles. This is a reminder to prioritize your overall well-being. I hope that as men, we will continue to open up to one another, becoming vulnerable in order to share what we are going through. By sharing and by supporting each other, we can learn and grow together. You are not alone, and when you fall, you can still get up and stand tall.
From one broski to another, you are loved and appreciated. I hope this mindset carries into December and beyond.
Mindfulness
Our content team recently released a handful of articles on mindfulness, a practice that I believe provides a good opportunity for stress release and self-reflection:

MDPI Insights: The CEO’s Letter #5 - OA Week, UK, and Strategy
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Open Access Week 2023 – the Global Drive to Open Continues
As the world's largest open-access (OA) publisher, we believe that unrestricted access to research findings is the cornerstone of transparency, efficiency, and quality control across scientific disciplines. At MDPI, we provide free, immediate access to scientific papers, empowering scientists to examine, validate, replicate, and build upon existing results. This minimizes redundancy, optimizes resources, and fosters innovative approaches.
International OA Week, held from 23 to 29 October 2023, provided a unique opportunity to link the global movement toward open sharing and open science with the progress of policy changes at the local level. Our mission, during OA Week and all the year round, is to offer educational resources highlighting the benefits of open-access publishing. The MDPI Blog is a valuable resource for information on open access and open science.
Core principles of OA publishing
Accessibility, transparency, and collaboration are core principles of OA publishing. OA aims to break down barriers that have traditionally restricted research access, ensuring that knowledge is available to all, regardless of financial situation or institutional affiliations. Our commitment to diverse pathways for OA publishing worldwide includes discounts for researchers. You can learn more about how MDPI supports scientific communities here.
One of the key strengths of OA publishing is its ability to facilitate interdisciplinary research. By removing paywalls and promoting knowledge-sharing across disciplines, OA encourages collaboration and innovation. Researchers from various fields can access and build upon each others’ work, fostering a holistic approach to addressing complex global challenges.
OA holds the potential to democratize knowledge, advance science, and drive positive societal change.
Policy driving change
Governments, institutions, and funding agencies have recognized the transformative potential of OA and have implemented policies to promote it. These policies often require publicly funded research to be made openly accessible, accelerating the growth of OA repositories and journals. Check out our spotlights on OA policies in the US, EU and China.
OA publishing is continuously evolving, with community-driven models and technologies shaping its future. Initiatives such as “Plan S” and “cOAlition S” promote OA publishing from the perspective of national funders, requiring grantees to publish their research openly. A new policy announced by the US administration last year mandates that, with effect from January 2026, all US federally funded research should be freely and immediately available after publication.
Additionally, preprint servers such as MDPI's Preprints.org, which allow researchers to share their findings before formal peer review, have gained popularity, enhancing the speed at which new knowledge is disseminated. The rise of blockchain technology is also being explored to ensure transparency and authenticity in scholarly publishing.
For more than two decades, OA publishing has been revolutionizing academic publishing by promoting accessibility, transparency, and collaboration. Its support for interdisciplinary research, evolving policies, and innovative practices all contribute to its growing influence in the global research community. As OA continues to expand, it holds the potential to democratize knowledge, advance science, and drive positive societal change.
MDPI is proud to lead the transition to open access.

Entropy Best Young Research Talk Award from Quantum 2023—From Foundations of Quantum Mechanics to Quantum Information and Quantum Metrology & Sensing—Winner Announced
We are pleased to announce that the Best Young Research Talk Award, sponsored by Entropy (ISSN: 1099-4300) for the conference “Quantum 2023—From Foundations of Quantum Mechanics to Quantum Information and Quantum Metrology & Sensing”, was granted to Dr. Luca Vannucci from the Technical University of Denmark (DTU). Congratulations!
“Two-color excitation for highly efficient and indistinguishable single-photon sources”
Abstract: Photonic quantum technologies—such as quantum computers, simulators, and networks—rely on multi-photon interference to process information and, therefore, on the availability of efficient sources of indistinguishable single photons. For a single-photon source (SPS) with photon output 
(defined as the number of photons delivered per excitation trigger) and degree of indistinguishability 
, the rate of successful 
-photon interference scales as 
. Thus, for scalable quantum information processing, the source's figure of merit 
must be increased as close as possible to 1.
To this end, much attention has been focused on optimizing the SPS efficiency (and thus the photon output ) via the optical design of the electromagnetic environment around a quantum dot (QD) emitter, and on understanding the decoherence effects on the indistinguishability, such as the coupling to lattice vibrations. For instance, Refs. [1] and [2] have illustrated the trade-off between and dictated by phonon scattering, and have shown how to push such a trade-off to the maximum performance via photonic engineering. However, most studies assume to initialize the quantum emitter to the excited state with 100% probability, which is a highly non-trivial task. The missing element is now a pumping scheme that excites the emitter with near-unity fidelity and that is compatible with the requirements for scalable quantum technologies.
Here, we identify such a key component by demonstrating that two-color excitation allows the pushing of the figures of merit to the maximum performance, provided that the so-called phonon decoupling regime is reached. Specifically, we examine both a dichromatic “red-and-blue” configuration (see Figure, panel a), with one laser pulse on the blue side and one on the red side of the spectrum with respect to the emitter [3, 4], and the so-called SUPER protocol [5, 6] with two laser pulses on the red side of the spectrum (b). In both cases, we identify the conditions to remove unwanted phonon scattering in the excitation process and achieve arbitrarily high population inversion for quantum emitters embedded in bulk semiconductors. As a specific example, we demonstrate that a state-of-the-art micropillar SPS driven with our scheme can generate up to 0.95 photons per excitation trigger into the collection optics with even better indistinguishability than the one obtained under resonant excitation [7].
Finally, we shed light on the working principle behind two-color excitation and the role of the two pulses. Going beyond the semi-classical approximation, we present a fully quantum-mechanical model for an emitter interacting with two field modes, which shows that the excitation dynamics involves an exchange of photons between the emitter and both field modes, and that it is, therefore, a multi-photon process [8].

MDPI Insights: The CEO’s Letter #4 - MDPI Presence in China
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Open Access in China
It is Saturday, 23 September, and I have just returned from an unforgettable 12-day trip to China, visiting our main offices in Beijing and Wuhan. In the wake of a packed and very enjoyable agenda of internal and external meetings, I would like to use this edition of the CEO Letter to showcase how MDPI supports the scholarly community in China.
Coincidentally, Jack McKenna, Communications Associate from MDPI’s corporate content team, has just released a blog article discussing China’s open access (OA) policy. It is a timely read, providing a concise overview of the development of the OA movement in China and reflecting on its future. I shall draw some content from Jack’s piece and use this edition of the CEO Letter to highlight the various ways in which MDPI is involved in this market. And it would be remiss of me not to include some pictures and highlights from my travels!
Open Access Policy in China
As per Jack’s post, in 2020, China became the world’s leading producer of research articles. Today, China is experiencing a “substantial growth rate in OA [Open Access] publication”. This growth is supported by the State’s commitment to research & development and its policy “requiring the promotion of open science”.
Over the past two decades, there have been gradual developments in China’s OA framework, with repositories and platforms being developed in a consistent manner. Currently, key institutions across China – including the National Science Library, the National Science and Technology Library, and the Natural Science Foundation of China – support OA. The State aims to establish consistent policies across government agencies – a framework for a more encompassing embrace of OA across institutions.
In China, the number of subscription-only articles decreased by nearly 30% over the 10-year period of 2011–2021, while gold OA increased by 22%. Between 2017 and 2020 alone, China published 800,921 academic papers in an OA format.
In 2023, as the leading publisher of academic research, China is pursuing “self-reliance”. Therefore, the State will be establishing consistent policies across government agencies, including those related to OA. Additionally, it will want to ensure that Chinese people can access the research that is supported by Chinese funding and produced by Chinese academics. For this reason, “Open Access is a matter of priority in China”.
MDPI Offices in China
While the history of MDPI begins in Basel, Switzerland, the story of MDPI’s founder is very much rooted in China. Dr. Shu-kun Lin, Founder and President of MDPI, graduated with a BSc from Wuhan University in 1982. He also studied physical chemistry at the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (1982–1986; MSc in 1985), and at the University of Louisville, USA (1987–1989). Dr. Lin completed his doctorate in organic chemistry at the Swiss Federal Institute of Technology (ETH-Zürich) in 1992.

Our Strength is in Our People
With over 6,000 MDPI staff, across 20 offices in 11 countries, MDPI is able to offer authors responsive and efficient round-the-clock support, enabling a rapid publication process.
In my experience, stakeholders are genuinely surprised when they realize the extent of our global operations. My response is to reiterate that our people are our strength. This is why we have fast and efficient processes and top-notch responsiveness. Our global presence ensures that your manuscript is constantly attended to, rather than sitting on someone’s desk. We prioritize our authors’ needs and act quickly to move things through the various stages of publication. MDPI is built on speed, convenience, and competence, which I believe are core pillars for success in any industry. We continually strive to improve our systems and processes on the basis of these core strengths. We literally have over 6,000 staff worldwide dedicated to serving your needs. It’s not magic: it’s people; it’s real.

Meeting with the Society of Chinese University Journals (CUJS)
Prof. Tieming Zhang (President of CUJS, centre) and MDPI colleagues at CUJS office.
I am pleased to have participated in some highly productive meetings during my visit to China, including one with the Society of Chinese University Journals (CUJS). The meeting involved Prof. Tieming Zhang (President of CUJS), Assoc. Prof. Xin Zhang (Vice President and Secretary General), and Dr. Fei Gao (Executive Member of CUJS). Alongside my colleagues Dr. Guoshi Liu, Dr. Giulia Stefenelli, and Anita Sun, I represented MDPI and held an open discussion to address any questions regarding OA and MDPI.
We discussed several methods for collaboration, including a workshop on the future of peer review, MDPI sponsoring a funding grant for early-career researchers, and transitioning journals from diamond to gold OA. I am thankful for the opportunity to have met our colleagues at CUJS in person and feel very confident about our future collaborations in support of OA publishing in China.
MDPI hosts free academic seminars, author training sessions, and academic conferences as part of its commitment to enrich and support the scholarly community. CUJS often stages academic events (e.g., conferences, editor training, and editor competitions), and I believe there are great opportunities for CUJS and MDPI to collaborate accordingly.
Meeting with National Science Library, Chinese Academy of Sciences (NSLC)
Stefan Tochev (CEO, MDPI), Dr. Giulia Stefenelli (Chair of Scientific Officers, MDPI), Anita Sun (PR Manager, MDPI) and Dr. Guoshi Liu (Managing Director, MDPI) at the National Science Library, Chinese Academy of Sciences.
We also visited the NSLC Director, Xiwen Liu, and colleagues Ying Jin, Zhesi Shen, and Sichao Tong. Following our introductions, we gave a presentation on the history and editorial process at MDPI, discussing specific details related to MDPI’s business and data. We highlighted the status of our IOAP collaborations in China and the makeup of our author base, specifically in China, and drew attention to the fact that MDPI has published research by authors from every country in the world. We then discussed the design indicators, calculation methods and implementation purposes of the ‘Early Warning Journal List’ and how we can have open communication to provide any data regarding MDPI journals. I am pleased to report that we reached a consensus on future communications, and am grateful to NSLC for hosting us in their offices.
In-person meetings with stakeholders provide an invaluable opportunity to communicate what MDPI is about and the various ways in which we serve the scholarly community. While digital marketing and online communication are essential, they are no replacement for the understanding and trust that come about through in-person interactions.
The Numbers
As at September 2023, China holds the largest position in MDPI’s global market, ranking as the largest contributor to the total number of papers published by MDPI.
At this point in time, there were more than 847,000 China mainland scholars who have published with MDPI, 51 of whom are Section-Editors-in-Chief (SEiC) of MDPI journals, with seven serving as Editors-in-Chief (EiCs) for journals such as Air, Big Data and Cognitive Computing, Blockchains, Future, Nanoenergy Advances, and Targets.
Our growth and presence in China are a true testament to the service we provide to the scholarly community, and to the relationships we foster through collaborative activities. We look forward to continuing to support the growth of the scholarly community in China, providing a valuable and trusted experience with MDPI.

I spent approximately two weeks visiting some of our offices in China, and the first word that comes to mind when describing my experience is ‘hospitality.’ My colleagues and I were met with enthusiasm and delight at the airport by the Tongzhou Admin team (thank you, Jiale Shang, and thank you, Eric Wang, for keeping us organized on this trip!) and were taken care of with great attention. From hotels to transportation, dinners, and meetings, our stay was catered for perfectly.
Perhaps this is where MDPI’s focus on customers and service originates. At our core, we are a service company that provides a publishing platform for its authors. It’s therefore no surprise that authors consistently rate their experience with MDPI very highly.
95% of submitting authors rate their overall experience with the MDPI publication process as Excellent or Good (Springer Nature report 90%).
91% of submitting authors rate their overall experience with the MDPI peer review process as Excellent or Good.
Speed/Efficiency and Editorial Relationship are two key reasons underlying this high satisfaction score. ‘Editorial Relationship’ can be further explored, but in the past month, the most commonly noted aspects were the professionalism, kindness, availability, communicativeness, and personalized assistance provided by our editorial staff throughout the process. These attributes are at the core of our work across all our offices and continents.
Hospitality and Service
Just as our Chinese colleagues strove to keep us engaged by showing us the city sights (thank you, Thea Pan, and Jason Wu from the Wuhan Marketing team!) and sharing a variety of wonderful meals, our editorial staff are committed to serving our authors throughout their publishing journey. Our aim is to place the author at the centre of everything we do, eager to welcome our ‘guests’ and provide them with a pleasant publishing experience.
I asked my colleague Francis Wu (Senior Publisher, Wuhan office) where this hospitality originates. He responded that it is part of Chinese culture. I reflected long and deep on this answer. China is a vast country, and when visitors arrive, hosts want to ensure they feel welcomed and taken care of in order to maximize their time and visit. I can’t think of a better analogy for how I would want our authors to feel when they visit MDPI for their publishing needs. A company culture that prioritizes service, something that goes beyond products and productivity, and focuses on the overall experience. Over 6,000 people, across all MDPI offices, are ready, willing and able to go the extra mile for their colleagues and their customers. This is something I am truly proud of.

MDPI Insights: The CEO’s Letter #3 - Sustainability and Co-opetition
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Our Commitment to Sustainability
As a pioneer in academic open access publishing since 1996, MDPI has always been dedicated to facilitating scientific exchange across all disciplines. Our approach to open science is guided by principles such as Open Access (OA), Timeliness and Efficiency, Simplicity, High-Quality Service, Flexibility, and a commitment to Sustainability. This commitment involves preserving published papers for the long term and supporting the future of science through partnerships, sponsorships, and awards.
In this edition of the CEO Letter, I will delve into MDPI’s various sustainability initiatives. As a leader in OA publishing, we are able to provide the public with a significant amount of environment-related content at no cost.
MDPI and the Sustainable Development Goals (SDGs)
In 2020, the SDG Publishers Compact was launched to accelerate implementation of the SDGs by promoting content that informs, develops, and inspires action. MDPI joined this initiative in 2021 and subsequently launched the MDPI SDG Hub in 2022, offering free access to recent research within the scope of each of the 17 SDGs. We also support authors from underrepresented communities by waiving publication charges for selected SDG-related papers. Detailed sustainability practices and supported publications are available in the report under each Goal page.

Closing Thoughts
“Co-opetition”: Collaboration Plus Healthy Competition – A Visit to Elsevier
I firmly believe in fostering collaboration and at the same time promoting healthy competition within the academic publishing industry. The market offers ample room for publishers and related companies to provide valuable services and products that enrich the academic community. While MDPI is recognized for its efficient and streamlined processes –thanks to our over 6,000 colleagues, in-house tools, and initiatives that support the author journey – our ethos has always involved learning from and collaborating with other organizations.
MDPI’s Interaction with Elsevier
In January 2023, I had a brief conversation with Judy Verses, President of Global Academic and Government Markets at Elsevier, following her participation in a panel discussion at the Academic Publishers Europe event in Berlin. One of the highlights for me was Judy’s insight into the impact of research, particularly her emphasis on the role of collaboration, including policy and showing the impact of research to influence on funding decisions.
“Such collaborations drive forward-looking strategies to elevate our support for the scholarly community”
Judy and I resumed our discussion in August, when I visited Elsevier's office to review current projects, such as our recent agreement with Science Direct and the continued indexing of MDPI journals in Scopus (indexing database owned by Elsevier). We also explored possible opportunities for the future, including a potential collaboration to expand MDPI’s Scilit data infrastructure. This endeavour aims to aggregate and provide access to scholarly metadata encompassing journal articles, conference papers, books, preprints, and more. While these discussions are ongoing, the underlying principle remains that such collaborations drive forward-looking strategies to elevate our services and support for the scholarly community.
It was great that Judy and I acknowledged the merits of 'co-opetition,' a concept based of the belief that fostering cooperation alongside healthy competition can lead to shared advancements for both individual companies and the industry at large.
‘Fully OA’ Organizations Dedicated to Open Access
MDPI proudly aligns with the ‘Fully OA’ group, a collaborative initiative comprising nine organizations dedicated to Open Access. Our monthly meetings, including an OASPA representative, serve as platforms to share non-confidential information, resources, and projects. These gatherings also facilitate discussions on topics relevant to fully OA organizations. Occasionally, joint actions spring from these interactions, such as collaborative blog posts on pertinent subjects and joint statements, such as a recent response to the House Appropriations Committee.
This display of cooperation among competing entities forms a strategic alliance focused on nurturing the best interests of the OA publishing model.
As I wrap up this third edition of the CEO Letter, I encourage you to seize opportunities for collaboration and contribute to advancing our shared academic culture. As the African proverb has it, “If you want to go fast, go alone; if you want to go far, go together.”

Entropy Best ECR Presentation Award for CNS*2023 Workshop on Methods of Information Theory in Computational Neuroscience—Winner Announced
We are pleased to announce that the Best ECR (Early Career Researcher) Presentation Award, sponsored by Entropy (ISSN: 1099-4300) for CNS*2023 Workshop on Methods of Information Theory in Computational Neuroscience, was granted to Dr. Maria Pope from the Indiana University Bloomington, USA. Congratulations!
“Multivariate Information Theory Reveals Synergistic Subsystems of the Cerebral Cortex”
Abstract: One of the most well-established tools for modeling the brain is the functional connectivity network, which is constructed from pairs of interacting brain regions. While powerful, the network model is limited, as only pairwise dependencies are considered and potentially higher-order structures are missed. This talk will explore how multivariate information theory reveals higher-order dependencies in the human brain, presenting results obtained from applying recently introduced O-information to resting-state brain data to show that synergistic subsystems are widespread in the human brain. Highly synergistic subsystems typically sit between canonical functional networks. Maximally synergistic subsystems, found using simulated annealing to optimize for synergy dominance, typically comprise ≈10 brain regions recruited from multiple canonical brain systems. Results from partial entropy decomposition will be presented that further support the notion that canonical organizations of the brain focus largely on redundant information. Though ubiquitous, highly synergistic subsystems are invisible when considering pairwise functional connectivity, and our results suggest that highly synergistic systems do not fall along canonical system lines. In summary, it will be argued that higher-order interactions in the brain reflect an under-explored space, accessible with tools of multivariate information theory, that may offer novel scientific insights.

MDPI Insights: The CEO’s Letter #2 - Open Peer-Review and IJERPH
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Open Peer Review Reports
Continuing the topic of openness from my inaugural monthly CEO letter, in these Opening Thoughts, I highlight the growth and importance of open peer-review reports at MDPI. Open peer reports align with the principles of open science, making the publishing process more transparent and facilitating rigorous peer review.
MDPI journals operate an open peer-review option by default, allowing authors to publish review reports and author responses (often referred to as open reports) together with the published paper. Publishing the reviewer reports and author responses together with the article provides greater transparency and trust for readers, as this allows them to track the editorial decision-making process. Open peer-review also encourages reviewers and editors to provide high-quality comments, as these will be made public if the article is accepted for publication.
Start and Growth of Open Peer Review at MDPI
The MDPI journal Life was a pioneer in offering this opportunity to its authors in 2014. The first MDPI article with peer-review reports openly published was a review by the Nobel Laureate Werner Arber, in which the review reports were published as supplementary material. By 2018, open peer-review was available across all MDPI journals. As such, MDPI authors have embraced the open peer-review model, providing a steady increase in the number of MDPI articles. As of 2023, approximately one-third (34.0%) of MDPI articles were published with open review reports.
As at July 2023, the percentage of MDPI articles published with open peer review has increased to 36.2% of the total papers published in 2023 so far, indicating ongoing growth in adoption.
Open peer review continues to play a critical role in the assessment of the peer-review process in Life. For further insights, please see the recent editorial by Dr. Pabulo Henrique Rampelotto, the former Editor-in-Chief of Life, who spearheaded the implementation of the open peer-review process.
Benefits of Open Peer Review
The benefits of open peer review include increased transparency, trust and constructive feedback. To promote open communication further and increase the robustness of the peer-review process, we encourage reviewers to sign their reports so that their name appears on the review report (this process is referred to as open identity). The default option is for reviewers to remain anonymous; however, by signing the reports, reviewers receive direct credit for their contribution to the peer-review process and show their commitment towards open science.
As the leading open access publisher, MDPI remains committed to promoting open peer-review and encourages authors to choose this approach. Our goal is to provide a rigorous and transparent peer-review process that benefits the scientific community, and we believe that open peer-review is a vital step in fostering openness and collaboration in scientific communication.

Inside MDPI
MDPI Develops an Artificial Intelligence Tool to Enhance the Peer-Review Process
At MDPI, we believe that rigorous peer-review is the corner-stone of high-quality academic publishing. We are grateful to the scholars who generously dedicate their time to peer-review articles submitted to MDPI journals. Their contributions are invaluable to the advancement of science.
Peer-review is a critical part of the publication process, ensuring that MDPI upholds the highest quality standards for the papers we publish. Every manuscript submitted to our journals undergoes a comprehensive peer-review process conducted by subject-matter experts.
To further enhance our peer-review process, our Data Analytics team has developed an Artificial Intelligence (AI) tool designed to support the selection of reviewers. This proprietary tool utilizes Natural Language Processing (NLP), a specially designed AI language model, to extract information from the title and abstract of submitted papers. It then searches our database for similar manuscripts and suggests potential reviewers based on this analysis. Integrated with MDPI's submission system (SuSy), the AI tool cross-references the suggested candidates with our reviewer database to verify their invitation status and availability.
The goal of this tool is to provide better targeted peer-review invitations, reducing the number of emails sent for each paper and increasing the efficiency of our editorial staff.
In the near future, our Data Analytics team plans to deploy similar AI projects to improve other critical aspects of our services, offering an enhanced experience to our authors and readers.

The Future of IJERPH
On 5 July 2023, Prof. Dr. Paul B. Tchounwou, the founding Editor-in-Chief of IJERPH, along with five Section Editors in Chief (Prof. Dr. Germán Vicente-Rodríguez, Prof. Dr. Karl Goodkin, Prof. Dr. William A. Toscano, Prof. Dr. Jimmy T. Efird, and Prof. Dr. William Douglas Evans), gathered in Basel to discuss the future of the journal. The meeting provided an opportunity to address the recent decision by The Web of Science to delist IJERPH due to the journal failing the Content Relevance criterion, and propose best strategies that will ensure high scientific rigor as well as a clear scope and aim of IJERPH, going forward.
While the delisting is disappointing for IJERPH, as well as for our authors, academic editors, and the entire scientific community supporting our journal, we see it as an opportunity to reflect and prepare for the future direction of the journal.
Since its launch in 2004, IJERPH’s vision and mission have evolved to be more complete and comprehensive in engaging scientific communities. In light of this, we will refresh the journal’s aims and scope, ensuring they align with the organic expansion of IJERPH. Additionally, we will restructure the journal sections into broader categories, encouraging collaborative research and transdisciplinary approaches for authors. This is designed to foster collaboration and knowledge exchange among diverse fields, contributing to a holistic understanding of health promotion and disease prevention. We are confident that these next steps will enhance the scientific strength and societal impact of our journal.

MDPI’s Impact in Spain
During the past month, I had the opportunity to visit our new office building in Barcelona, where I met with our local colleagues to discuss the ways we serve the scholarly community, particularly in Spain. The multi-functional office plays a vital role in supporting various business needs, including editorial, design, conference management, data analytics, journal relationship management, publishing partnerships, and collaborations with societies.
Spain holds a significant position in MDPI’s global market, ranking as the fourth-largest contributor to the total number of papers published by MDPI as at July 2023, ranking next to Italy, the USA, and China, with Germany completing the top five.
The Numbers
Out of the 1,680,000 total MDPI articles published as at 25 July, almost 80,000 articles are contributed by Spanish authors, representing nearly 40,000 unique authors affiliated with Spanish institutions. Remarkably, over 6,300 of these authors hold editorial board member (EBM) positions within MDPI journals, with 30 of them serving as Editors-in-Chief (EiCs).
Our commitment to working with institutions is very evident in Spain, where we have successfully established over 40 Institutional Open Access Programs (IOAP) with esteemed institutions such as the University of Barcelona, the Autonomous University of Barcelona, Pompeu Fabra University, the University of Navarre, and Complutense University of Madrid.
Over the past five years, we have successfully organized eight in-person conferences in Barcelona, attracting over 1,150 registrations, with two forthcoming events scheduled for 2024. Barcelona's excellent connectivity to international airports makes it easily accessible to participants from around the world. Its welcoming atmosphere provides us with the perfect environment for knowledge-sharing, networking, and contributing to the local economy.
Our growth and presence in Spain are a true testament to the incredible service we provide to the scholarly community and the relationships we foster through responsive and collaborative communication. We look forward to continuing to support Spanish scholars, providing them a valuable and trusted experience with MDPI, the leader in open access publishing.

Entropy Best Presentation Award at the 8th Workshop on Economic and Financial Networks—Winner Announced
We are pleased to announce the winner of the Best Presentation Award that Entropy (ISSN: 1099-4300) sponsored at the 8th Workshop on Economic and Financial Networks, held on 10 July 2023, in Vienna, Austria. Congratulations to Zsófi Zádor!
“The Effect of Value Chain Importance on Regional Economic Recovery” by Zsófi Zádor
This talk investigated the link between value chain importance and economic growth for the EU24 regions between 2008 and 2018. It found that relying more on GVCs worsened regional growth during the financial crisis but led to higher growth in the long run. The results contribute to the literature on regional resilience and the public debate on the impact of shocks and the desirability of GVCs. Furthermore, by separately analysing the importance of global and regional value chains, it contributes to the discussion on the effect of regionalisation and provides insights into how the re-configuring of value chains may affect regional growth.

MDPI Insights: The CEO’s Letter #1 - Open Access and Impactful Research
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
The Future is Open, and MDPI is Leading the Way
I strongly believe in a future that embraces openness, where open source, open information, and open access (OA) take center stage. This belief that led me to join MDPI in 2020, and I am honored to have recently been appointed as Chief Executive Officer (CEO). In this capacity, and operating in close liaison with Dr. Lin and MDPI’s senior management, I shall work to build on Dr. Lin’s achievements of the past quarter-century. In this role, I will focus on communication initiatives to promote MDPI's remarkable work and continue to build our company as a trusted leader in OA publishing. For over two decades, MDPI has been at the forefront of reshaping the academic publishing landscape, with OA surpassing subscription-based publishing in 2020. This trajectory is deeply rooted in our history and reflects our unwavering commitment and vision for an open future.
1 Million Published Articles
2023 began with a remarkable achievement for MDPI, as we became the first OA publisher to reach the milestone of 1 million published articles. This represents 2.7 million unique authors who have trusted us with their work, or about a third of all researchers worldwide. As the world's most cited OA publisher, we are proud in sharing these significant milestones.
Our mission remains unchanged: to make science open and accessible to all. We understand the importance of knowledge access, empowering researchers to stay at the forefront of a rapidly changing world. Our diverse range of journals covers a wide spectrum of disciplines, offering cutting-edge insights, trusted tools, and crucial knowledge to address global challenges.
Liberating Science
As the world’s leading OA publisher, MDPI is actively liberating science. We are committed to eliminating the frustrations researchers and the general public face when accessing information, ensuring it is not locked behind paywalls. We firmly believe that everyone has a right to information, and our commitment to open access publishing drives our work.
In this inaugural edition of Insights: The CEO's Letter, I draw inspiration from the upcoming 20th anniversary of the Berlin Declaration on Open Access. Its stated mission reminds us that true impact is achieved when knowledge is widely and readily available to society:
"Our mission of disseminating knowledge is only half complete if the information is not made widely and readily available to society”
Impactful Research
MDPI Publishes Impactful Research: Recognized by Leading Indexing Databases
MDPI journals are indexed in every single top database in the world.
As of June 2023, we have 214 journals indexed within Web of Science, 223 indexed within Scopus, 87 indexed within PubMed and PMC, and 17 indexed within MEDLINE, and these numbers increase every month. We constantly strive to expand the coverage of our journals within leading multi-disciplinary and scope-specific databases, resulting in an incredibly broad range of journals that are indexed within a variety of databases. MDPI has active relationships with approximately 65 well-known databases around the world, and we continue to expand our portfolio every year so that your work can be found, cited, and referenced with ease.
Continued Growth of MDPI Journals
The 2022 Scopus and Web of Science journal citation metrics were officially released in June, and I am pleased to report that 31 MDPI journals received their first CiteScore, taking the total number of journals with a CiteScore to 216. The number of MDPI journals receiving an Impact Factor (IF) also continues to grow with 111 receiving their first, by being covered in the ESCI, bringing our total number of journals with an IF to 208 of which 41 journals received an IF above 4.0. Looking at 2022 CiteScores in the Scopus database, 80% of MDPI journals have a score that ranks them in Q1 or Q2 in at least one subject category.
Publishing impactful science would not be possible without all of our authors, editors and reviewers. Thank you for your contribution and continued support! Together we share the latest scientific insights faster and ensure that your work is accessible to all.

Coming Together for Science
The First International Conference on Antioxidants: Sources, Methods, Health Benefits and Industrial Applications
In this edition of ‘Coming Together for Science,’ I am pleased to highlight the First International Conference on Antioxidants organized by our conference team in the beautiful city of Barcelona, Spain. The conference attracted over 130 attendees, who engaged in 42 talks, and 89 poster presentations spread across several sessions.
Working Together
Under the leadership of Prof. Dr. Alessandra Napolitano (Department of Chemical Sciences, University of Naples ‘Federico II’, Naples, Italy) and Prof. Dr. Rosa M. Lamuela Raventos (Department of Nutrition, Food Sciences and Gastronomy, University of Barcelona, Spain) as chairs, and supported by the committee members, 10 invited keynote speakers, poster presenters, and all the attendees, this dedicated group of academics came together to discuss the natural sources, methodologies, health benefits, and industrial applications of antioxidants.
Especially noteworthy is the positive feedback received from attendees, with 94% rating the overall organization of the conference as good or excellent. I particularly love the picture above, capturing the gathering of some of the participants. You can browse through more photos in the event gallery located here.

"Thanks a Million!" – One Million Articles Published in MDPI Journals
MDPI has just become the first open access (OA) publisher to reach the milestone of one million articles published. That is one million articles freely available to all, to circulate and build upon! We are proud to share this special moment with the global scientific community.
This landmark has been reached thanks to the immeasurable support of more than 600,000 expert reviewers, 66,000 editorial board members and 6700 hard-working colleagues across MDPI’s global offices.
Within more than 25 years of publishing, our journals received 2.1 million manuscripts and generated 4.6 million peer review reports to get to one million papers published.
Reaching the milestone of one million articles published reinforces our mission to remove any existing barriers and to make scientific research accessible to all. Since its inception, MDPI’s goal has been to create reliable processes to make science open. This is a path towards facilitating the dissemination of novel insights in scientific communities.
Regular feedback from authors and reviewers shows that our service is greatly appreciated and needed. At the same time, the feedback helps us identify areas for further improvement.
As it stands, a significant share of published research findings remain closed access. More than half of the content published with the most well-known legacy publishers stays behind a paywall, and that is not including articles published in hybrid OA journals, or made available months or years after publication.
A new policy announced by the US administration in August 2022 requires that, as of January 2026, all US federally funded research be made freely and immediately available after publication. While the new policy does not mandate articles be published under an open access license, it is aligned with the open access movement in removing all barriers to research. Similarly, some of the most advanced research institutions in the world intend to have all funded research articles published in open access by 2025.
MDPI is proud to be the leading agent of the transition to open access.
"Thanks a Million" to all the contributors!

Paper: “C110: CT-Guided Automatic Path Planning for Lung Puncture”
by Jianquan Zhong, Ling Tang, Ruizhi Hao, Jinyang Shen, Jiayu Zhang, Yuhang Gong, and Jing Zhang
An automatic CT image-based path planning method for lung puncture surgery is proposed due to the high failure rate, time consumption, and high radiation dose of the existing percutaneous lung puncture surgery. The method described in this paper implements automatic organ segmentation of chest CT images. It defines six constraining conditions combined with clinical a priori knowledge to find the optimal puncture path using a multi-objective Pareto optimization method. The rationality and validity of the method were validated based on 25 sets of clinical lung mass data. Experimental results show that the optimal paths found by this system all meet the clinician's surgical requirements.

“Statistical analysis of a microscopic financial dataset for the long-range correlation of the order flow” by Kiyoshi Kanazawa
In the financial market, it is an established fact that order flow exhibits persistence: if you observe a buy (sell) order, you will likely observe a buy (sell) order even in the future. This phenomenon, called the long-range correlation (LRC), has been a topic under debate regarding its microscopic origin. One of the promising hypotheses in econophysics is the order-splitting hypothesis: in financial markets, many traders split their large metaorders into a series of small child orders. Because their order signs are kept the same during splitting, the market order sign has a (slight) predictability. This hypothesis was mathematically formulated by Lillo, Mike, and Farmer (LMF) in 2007. Interestingly, the LMF model predicts a quantitative relationship between a microscopic parameter (the power-law exponent of the metaorder-size distribution) and a macroscopic parameter (the power-law exponent for the order-sign autocorrelation function). In this talk, we present our statistical analysis to confirm the LMF prediction using a microscopic Tokyo Stock Exchange dataset. We develop a statistical method to measure the power-law exponents with less statistical bias, and we apply the method to confirm the LMF prediction. A long-standing problem in econophysics has been solved by our detailed data analysis of a microscopic financial dataset.

“Entanglement Witnessing for Lattice Gauge Theories”
by Veronica Panizza
Abstract: LGTs are at the core of fundamental physics and, recently, substantial theoretical and experimental efforts have gone into simulating LGTs using quantum technologies. In the quantum realm, entanglement plays a crucial role and its detection can be efficiently performed using entanglement witnesses. Yet, entanglement witnessing in LGTs is extremely challenging due to the gauge constraints, that severely limit the operators that can be employed to detect quantum correlations. In this work, we develop the theoretical framework of entanglement witnessing in lattice gauge theories and, by way of illustration, consider bipartite entanglement witnesses in a U(1) LGT (with and without fermionic matter). Our framework, which avoids the costly measurements required, e.g., by full-tomography, opens the way to future theoretical and experimental studies of entanglement in an important class of many-body models.
“Criticality and Compatibility in Multi-Parameter Quantum Metrology”
by Giovanni Di Fresco
Abstract: Many-body systems near a quantum phase transition (QPT) exhibit several properties which makes them appealing for metrological purposes. Indeed, it is now well established that the divergences of the quantum Fisher information (QFI) observed near a QPT can be used to increase the precision in the estimation of a parameter. Meanwhile, when it comes to the simultaneous estimation of multiple parameters, the benefits of criticality are much harder to analyze due to possible incompatibilities arising from the Heisenberg uncertainty. This involves the use of quite convoluted quantities, as the Holevo-Cramer-Rao bound, which are generally difficult to evaluate. Here we study the quantumness (R), a scalar index, which provides an asymptotic bound on the compatibility of a metrological scheme. The advantage of this approach is that R can be easily evaluated once the QFI and the mean Uhmlann curvature are known. Moreover, a scaling analysis of R reveals that many-body criticalities generally improve the compatibility in a multi-parameter framework. We also evaluate R in different representative systems, such as Ising chain and XY chain, in which we find this positive criticality effects.

“Efficient representations of spatially variant point spread functions in Bayesian imaging algorithms”
by Vincent Eberle, Philipp Frank, Julia Stadler, Silvan Streit, Torsten Enßlin
Bayesian imaging algorithms are becoming increasingly important in, e.g., astronomy, medicine, and biology. Given that many of these algorithms compute iterative solutions to high-dimensional inverse problems, the efficiency and accuracy of the instrument response representation are of high importance for the imaging process. For this reason, point spread functions, which make up a large fraction of the response functions of telescopes and microscopes, are usually assumed to be spatially invariant in a given field of view and can thus be represented by convolution. For many instruments, this assumption does not hold and degrades the accuracy of the instrument representation. We discuss the application of butterfly transforms, which are linear neural network structures whose size scales with the number of data points subquadratically. Butterfly transforms are efficient by design since they are inspired by the structure of the Cooley–Tukey Fast Fourier transform algorithm. We combine them into butterfly networks in several ways, compare the different architectures with respect to their performance, and identify a representation that is suitable for the efficient representation of a synthetic spatially variant point spread function with up to a 1% error.

“Modelling of aortic dissection with Beta random fields and uncertainty propagation with a Bayesian variational auto-encoder”
by Sascha Ranftl, Malte Rolf-Pissarczyk, GloriaWolkerstorfer, Antonio Pepe, Jan Egger, Gerhard A. Holzapfel, Wolfgang von der Linden
In this work, we create a stochastic constitutive model for arterial tissue mechanics and utilize deep learning surrogates in order to facilitate the ensuing propagation of uncertainties to the Cauchy stress fields resulting from tissue response to a mechanical load. In particular, "aortic dissection" is a dangerous disease that is linked to the stochastic and spatially heterogeneous degradation of the elastin fibers in aortic tissue. Here, this degradation is modeled as a "Beta" random field, i.e., a random field for which every marginal follows a Beta distribution, through a suitable combination of auxiliary Gaussian random fields. Based on this, the Cauchy stress fields in the tissue are computed using a finite element method in response to a mechanical load. Due to the stochasticity of the constitutive model in the input parameters, it is necessary to propagate these uncertainties to the computed mechanical Cauchy stress fields in order to make the simulations interpretable. The prohibitive computational effort of this latter step makes uncertainty propagation with direct sampling infeasible, instead requiring a surrogate model to be learned from a small number of samples from the finite element simulation. The structure of the input data, i.e., "Beta" random field realizations of the tissue's fibers degradation, and the output data, i.e., resulting mechanical Cauchy stress fields, define a problem similar to image-to-image (I2I) regression. This I2I problem structure suggests a convolutional neural network as a surrogate that is well-suited for learning the relationship between the spatial correlations. Here, we chose a Bayesian Variational Auto-Encoder (B-VAE) architecture. After training with Stein Variational Gradient Descent, the B-VAE can subsequently predict approximate Cauchy stress field samples from "Beta" random field samples several orders of magnitude faster, and with non-parametric Variational Inference, it can estimate the PDF of the predicted mechanical Cauchy stress fields. The study is presented within the framework of a rigorous Bayesian analysis. The results quantify the precision of such biomechanical simulations, and biologically relevant implications such as tissue rupture probabilities can be quantified.

"Delayed Choice and Bohmian Trajectories Investigated with Entangled Photons in a Double Slit"
by Jan Dziewior
Bohmian mechanics, a hidden-variable interpretation of quantum mechanics, ascribes reality to the positions and momenta of quantum particles at the cost of a non-local ontology. Thus, contrary to standard quantum mechanics, it allows one to conceive of definite particle trajectories while being fully compatible with the standard theory in all empirical predictions. Nevertheless, the plausibility of the Bohmian picture was called into question by a double-slit Gedankenexperiment conducted by Englert et al. [1], which initiated a lively controversy. While most of the proponents of Bohmian mechanics agreed with the predictions of Englert et al., their conclusions have been criticized. Here, the experimental realization of this Gedankenexperiment is presented. The conditions for the occurrence of so-called “surrealistic” trajectories are realized by using a pair of entangled photons, where one of the photons is sent into an optical double-slit interferometer. The average trajectories are recorded using a method inspired by weak measurements [2,3]. By avoiding the measurement of the second photon as long as the trajectories of the first one are measured, it is possible to realize a delayed choice scenario, fully illustrating the contrasting inferences of standard and Bohmian quantum mechanics.

“Inconsistency of linear dynamics and Born's rule”
by Lotte Mertens
Modern experiments conducted using nanoscale devices come ever closer to bridging the divide between the quantum and classical realms, bringing experimental tests of objective collapse theories that propose alterations to Schrödinger’s equation within reach. Such objective collapse theories aim to explain the emergence of classical dynamics in the thermodynamic limit and hence resolve the inconsistency that exists within the axioms of quantum mechanics when assuming measurements can be described by quantum mechanics as well. Here, we show that requiring the emergence of Born’s rule for relative frequencies of measurement outcomes without imposing them as part of any axiom implies that such objective collapse theories cannot be linear. Previous suggestions regarding the proof of the emergence of Born’s rule in classes of problems that include linear objective collapse theories are analyzed and shown to include hidden assumptions.

“Estimating Information Transfer In Vitro: Results from Barrel Cortex” by Fleur Zeldenrust
Understanding the relation between (sensory) stimuli and the activity of neurons (i.e., ‘the neural code’) lies at the heart of understanding the computational properties of the brain. However, quantifying the information between a stimulus and a spike train has proven to be challenging due to the limited life span of a cell in an in vitro setup. In 2017, in this workshop, I presented a new in vitro method to measure how much information a single neuron transfers from the input it receives to its output spike train. This method has the advantage that it is fast (~10 minutes) compared with traditional methods. This decrease in recording time is obtained by generating an input by an artificial neural network that responds to a randomly appearing and disappearing ‘sensory stimulus’: the hidden state. The low entropy of this hidden state allows for a fast estimate of transferred information. Using this method, we have now recorded over 850 trials in almost 300 inhibitory and excitatory neurons of the barrel cortex, using different pharmacological modulations (including dopamine, acetylcholine, and serotonin receptor agonists). Here, I presented the first conclusions of this large database of recordings and showed how this method can be extended to dynamic clamp and the effects this has on modeled neurons.
"Embedding Optimization Reveals Long-Lasting History Dependence in Neural Spiking Activity" by Lucas Rudelt
Information processing can leave distinct footprints on the statistics of neural spiking. For example, efficient coding minimizes statistical dependencies on spiking history, while temporal integration of information may require the maintenance of information over various timescales. To investigate these footprints, I presented an approach that quantifies history dependence within the spiking of a single neuron, using mutual information between the entire past and current spiking. Applying this approach to extracellular spike recordings, we found that both the strength and the timescale of history dependence showed striking differences between different neural systems. In conjunction with recent highly parallel spike recording techniques, this approach could yield valuable insights into how information processing is organized in the brain.

Title: “Chaotic Dynamics of the Clock Mechanism”
For centuries, the mechanical pendulum clock has been one of the primary means of measuring time. Its central part is a damped pendulum, kept in motion by the exciting force, the nature of which depends on the type of clock mechanism. The mechanism supplies energy to the pendulum and is simultaneously regulated by it; it is a special case of a self-excited oscillator, and the current feedback makes the dynamics of the system non-linear and often chaotic, with a fractal attractor. In the history of clock development, most attempts to improve the precision of timing have been based on reducing the influence of non-linear effects by minimizing the interaction between the pendulum and the mechanism—so that it is a good approximation of a mathematical free pendulum. A completely different approach was proposed in 1722 by John Harrison. In its construction, the pendulum is in constant contact with the mechanism and vibrates with a very large amplitude. Thanks to modern numerical methods, it is possible to perform a detailed analysis of this type of system (D. Ziemkiewicz, Phys. Rev. E 2021, 103, 062208). It can be shown that under appropriate conditions (correctly identified by Harrison), one can obtain an error of indications at the level of a few seconds per year, which is an unattainable value for other types of mechanical clocks.

“Self-Organised Criticality in High-Frequency Finance: The Case of Flash Crashes”
With the rise of computing and artificial intelligence, advanced modeling and forecasting has been applied to High-Frequency markets. A crucial element of solid production modeling though relies on the investigation of data distributions and how they relate to modeling assumptions. In this work, we investigate volume distributions during anomalous price events and show how their tail exponents <2 indicate a diverging second moment of the distribution, i.e., variance. We then tie the dynamics of flash crashes to self-organised criticality. The findings are of great relevance for regulators and market makers as they advocate for rigorous heavy-tailed modeling of risks and changes in regulation to avoid simultaneous liquidity withdrawals and hard risk constraints which lead to synchronisation and critical events.

Open Access Week 2021 | It Matters How We Open Knowledge: Building Structural Equity, 25–31 October
Founded in 1996, MDPI was one of the first fully Open Access publisher. Over 25 years MDPI has grown to become the largest Open Access publisher globally, publishing over 160,000 articles across more than 350 journals in 2020. At the core, MDPI was founded in response to a pressing need of fast publication and inclusion. The scholar was set at the centre of the publication process for the first time. Acting as a service provider, rather than a product provider, MDPI exists to help scientists achive their objective to disseminate research results. At MDPI, we believe scientists deserve a better service from the publishing world.
The International Open Access Week (Open Access Week), founded by the SPARC (the Scholarly Publishing and Academic Resources Coalition) Alliance and student partners in 2008, has been successfully running for 13 years. As an advocate and pioneer of open access publishing, MDPI actively responds to the call of International Open Access Week. This year’s theme of “It Matters How We Open Knowledge: Building Structural Equity” highlights the Recommendation’s call for equitable participation from all authors and readers.
For the last 25 years, MDPI has been committed to disseminating open research. Here is a video showing MDPI’s Commitment to Equity, Inclusion and Diversity for More than 25 Years.
International Open Access Week is an important opportunity to catalyze new conversations, create connections across and between communities that can facilitate this co-design, and advance progress in the building of more equitable foundations for opening knowledge—discussions and actions that need to be continued, year in and year out. MDPI has always aimed to provide professional and efficient publishing services to scholars around the world.
Our mission is to make scientific research accessible to everyone; this year, we interview and hold discussions with open science ambassadors on how to build an equal and inclusive environment for open science. Academic editors help us collaborate with more institutions to advocate for open access ideas.
Besides this, our scientific community is a key driver of our success and MDPI’s remarkable growth. Despite the pandemic, we have prepared online conferences and workshops to gather scholars from different communities.
The Basel Sustainable Publishing online forum provides an equal opportunity for stakeholders and researchers from multi-cultural environments to exchange ideas and eliminate barriers to participation.
Conference date: 25 October 2021, online
Conference website: https://bspf2021.sciforum.net/
Main topics: MDPI discusses the current dilemma of open access science from various perspectives such as governments, libraries, and publishers, and related measures on how to change the status quo of discrimination from a global perspective.
We aim to support equality, inclusion, diversity, and accessibility in scholarly communications. We collaborate with universities and key laboratories and have scholarly communications with researchers, teachers, and students on open access workshops.

The Nobel Prize in Physics 2021 was awarded to Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi. One half of the prize was awarded jointly to Professor Manabe and Professor Hasselmann for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming, according to the Nobel Prize committee, while the other half of the prize went to Professor Parisi for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales. The three physicists contributed to the understanding of chaotic and apparently random phenomena.

"The discoveries being recognised this year demonstrate that our knowledge about the climate rests on a solid scientific foundation, based on a rigorous analysis of observations. This year’s Laureates have all contributed to us gaining deeper insight into the properties and evolution of complex physical systems", said Thors Hans Hansson, chair of the Nobel Committee for Physics.
Manabe and Hasselman laid the foundations for the climate models used by scientists today. They were among the first to distinguish between climate phenomena on the one hand and random occurrences of the weather on the other hand, and to assess the impact of human activities on the climate from the beginning of the 20th century.
Parisi's novel studies involved identifying hidden patterns in disordered complex materials called spin glasses, a special type of metal alloy in which iron atoms, for example, are randomly mixed into a grid of copper atoms. He constructed a mathematical description of the apparently random behavior of spins. His findings not only impacted physics, but also mathematics, biology, neuroscience and machine learning, because these felds include problems which are related to so-called geometrical frustration.
We send our congratulations to the Nobel Laureates, especially to Giorgio Parisi, who was a one-time author in Entropy (with Juan J. Ruiz-Lorenzo et al.): “Spin Glasses in a Field Show a Phase Transition Varying the Distance among Real Replicas (and How to Exploit It to Find the Critical Line in a Field)”.

MDPI Joins SDG Publishers Compact
UN's 17 Sustainable Development Goals (SDGs) are the blueprint to achieve a better and more sustainable future for all. In 2020 the SDG Publishers Compact was launched, aimed to inspire publishers and accelerate progress to achieve the 17 goals by 2030. Members of the programme are committed to support the publication of materials that will promote and inspire actions towards SDGs.
MDPI is an eager advocate of SDGs and has already been supporting the programme by creating Special Issues and publishing a series of books on SDGs prior to joining the Compact in 2021. MDPI's Sustainability Foundation initiated the World Sustainability Awards in 2016. We fully support UN's goals to promote sustainable actions that make the world a better place for all and, as part of its commitment, we will focus our actions on SDG10: Reduced Inequalities whilst promoting all 17 SDGs. For more details, please visit the programme’s website: https://www.un.org/sustainabledevelopment/sdg-publishers-compact/.
Joining this initiative was a unanimous decision. MDPI has in its core values the dissemination of science for all, breaking the wall between research access and under-represented members of the scientific community and the general population. To support this initiative further and continue to support under-represented scientists, MDPI will take a series of actions that will be announced once ready.
The first action MDPI takes is to nominate Dr. Liliane Auwerter as the coordinator of the programme. Dr. Auwerter studied Environmental Process Technology (UTFPR, Brazil), obtained her MSc degree in Water and Environmental Engineering (University of Surrey, UK) and in 2020 completed her PhD in self-healing low-friction materials for water transport (Imperial College London, UK), always focusing on diverse scientific projects that would potentially bring sustainability to industrial processes. As a student in Brazil, she engaged in volunteering activities focused on environmental education and took part in the Millennial Development Goals meetings held at the university.

Entropy | Best Contribution Award for 2021 International Workshop “Open Quantum Dynamics and Thermodynamics”—Winner announced
We are pleased to announce that the Best Contribution Award sponsored by Entropy for 2021 International Workshop Open Quantum Dynamics and Thermodynamics was granted to Dr. Martí Perarnau-Llobet at University of Geneva. Congratulations!
“Optimal Finite-Time Carnot Cycle” by Marti Perarnau-Llobet
We considered the optimization of a finite-time Carnot engine characterized by small dissipations. We bound the power with a simple inequality and showed that the optimal strategy is to perform small cycles around a given working point, which can be thus chosen optimally. Remarkably, this optimal point is independent of the figure of merit combining power and efficiency that is being maximized. Furthermore, for a general class of dynamics, the power output becomes proportional to the heat capacity of the working substance. Since the heat capacity can scale supra-extensively with the number of constituents of the engine, this enables us to design optimal many-body Carnot engines, reaching maximum efficiency at finite power per constituent in the thermodynamic limit.

MDPI adopts C4DISC principles to improve diversity and inclusion in scholarly communications
MDPI is proud to adopt the principles of the Coalition for Diversity & Inclusion in Scholarly Communications (C4DISC) to support building equity, inclusion, diversity, and accessibility in scholarly communications.
The C4DISC represents organizations and individuals working in scholarly communications and is focused on addressing issues of diversity and inclusion within the publishing industry.
MDPI’s Managing Editors encourage the Editors-in-Chief and Associate Editors to appoint diverse expert Editorial Boards. This is also reflective in our multi-national and inclusive workplace. We are proud to create equal opportunities without regard to gender, ethnicity, geographic location, sexual orientation, age, disability, political beliefs, religion, or socio-economic status. There is no place for discrimination in our workplace and editors of MDPI journals are to uphold these principles in high regard.
Representatives from C4DISC meet monthly, and have started to implement initiatives to shed light and improve on the lack of diversity in scholarly communications. Some of the initiatives include developing a joint statement of principles; conducting market research; providing training resources, best practices, toolkits, and documentation for our collective memberships; and establishing outreach programs, curricula, events, and publications.
The Coalition is committed to:
- eliminating barriers to participation, extending equitable opportunities across all stakeholders, and ensuring that our practices and policies promote equitable treatment and do not allow, condone, or result in discrimination;
- creating and maintaining an environment that respects diverse traditions, heritages, and experiences;
- promoting diversity in all staff, volunteers, and audiences, including full participation in programs, policy formulation, and decision-making;
- raising awareness about career opportunities in our industries to groups who are currently underrepresented in the workforce;
- supporting our members in achieving diversity and inclusion within their organizations.

Article Layout and Templates Revised for Future Volumes
At MDPI we have slightly revised the layout for articles to be published in the 2021 Volume, starting at the end of December 2020. As of today, the article templates available for download on ‘Instructions for Authors’ pages have been updated.
The most noticeable change can be found on the first page of the article, where a left-hand column has been created to include the following front matter elements: (i) the recommended citation style for the article, (ii) the publishing history, (iii) as well as the Creative Commons Attribution license used (iv) a standard note regarding affiliations. At the same time, the extra spacing on the left means the authors’ affiliations are now more clearly set apart than before. Other front matter key elements such as journal logo, article type, article title, authors, abstract and keywords remain unchanged.
The blank column on the left runs through all pages in an article; as a result, the main text is slightly more condensed, which improve reader friendliness for smaller screens. Small figures/tables are aligned on the left with standard indenture, while large figures/tables are centered and covering the full width of the page. The revised layout was applied in the article pictured below, to serve as an example:
1) Information is displayed in the left information bar.
2) In the main text, there is a blank column on the left.
3) Small tables/figures are aligned on the left, large tables/figures are centered.

Prof. Dr. Lamberto Rondoni Appointed Editor-in-Chief of the Section “Non-Equilibrium Phenomena” in Entropy
We are pleased to announce that Prof. Dr. Lamberto Rondoni has been appointed as the Editor-in-Chief of the new section “Non-Equilibrium Phenomena” in Entropy.
Lamberto Rondoni is a full Professor of Mathematical Physics at the Politecnico di Torino in Italy and holds secondary appointments at Università di Torino and INFN (Italian Institute for Nuclear Physics). He works in statistical physics, particularly on the subjects of fluctuations at the nanoscale and general non-equilibrium systems. Statistical mechanics aims at describing the physical properties of a macroscopic system on the basis of the behavior of its microscopic constituents [1]. The most developed part of statistical physics concerns equilibrium situations, but the majority of assumptions employed for systems at equilibrium have limited application for out of equilibrium phenomena, and dedicated tools are required. Recent efforts led by a number of scientists including Lamberto Rondoni have unveiled exciting new and rigorous results, which are collectively known as fluctuation relations [2–5]. These represent one of the few general, accurate descriptions achieved so far in non-equilibrium systems, covering a wide variety of phenomena and observables. Furthermore, these developments have led to numerous results concerning the response of the widest class of systems to perturbations. Currently, research in this field is of particular interest in bio- and nanosciences and technology, as well as in soft sciences (socio-economic, media and communications, etc.) in which the notion of proper equilibrium cannot be established and in which stationary states are characterized by large fluctuations.
We warmly welcome Prof. Dr. Lamberto Rondoni as the Editor-in-Chief of the section “Non-Equilibrium Phenomena”, and we look forward to Entropy achieving many milestones under his leadership. For further information on the journal section, please click:

“A Differentiable Measure of Pointwise Shared Information” by Abdullah Makkeh
Partial information decomposition (PID) of the multivariate mutual information describes the distinct ways in which a set of source variables contains information about a target variable. The groundbreaking work of Williams and Beer has shown that this decomposition cannot be determined from classic information theory without making additional assumptions, and several candidate measures have been proposed, often drawing on principles from related fields such as decision theory. None of these measures is differentiable with respect to the underlying probability mass function. Here, we present a novel measure that draws only on the principle linking the local mutual information to exclusion of probability mass. This principle is foundational to the original definition of the mutual information by Fano. We reuse this principle to define a measure of shared information based on the shared exclusion of probability mass by the realizations of source variables. Our measure is differentiable and well defined for individual realizations of the random variables. Thus, it lends itself, for example, to local learning in artificial neural networks. We show that the measure can be interpreted as local mutual information with the help of an auxiliary variable. We also show that it has a meaningful Möbius inversion on a redundancy lattice and obeys a target chain rule. We provide an operational interpretation of the measure based on the decisions that an agent should take if only given the shared information.
“Multi-Target Information Decomposition and Applications to Integrated Information Theory” by Pedro Mediano
The partial information decomposition (PID) framework allows us to decompose the information that multiple source variables have about a single target variable. In its 10 years of existence, PID has spawned numerous theoretical and practical tools to help us understand and analyze information processing in complex systems. However, the asymmetric role of sources and targets in PID hinders its application in certain contexts, like studying information sharing in multiple processes evolving jointly over time. In this work, we developed a novel extension of the PID framework to the multi-target setting, which lends itself more naturally to the analysis of multivariate dynamical systems. This new decomposition is tightly linked with integrated information theory and gives us new analysis tools as well as a richer understanding of information processing in multivariate dynamical systems.

"Fishy Business: Noise-Induced Schooling in Fish" by Richard Morris
I reported on our work concerning the dynamics of collective alignment in groups of the cichlid fish, Etroplus suratensis. Focusing on small-to-intermediate sized groups (10 < N < 100), we demonstrate that schooling (highly polarised and coherent motion) is noise-induced, arising from the intrinsic stochasticity associated with finite numbers of interacting fish. The fewer the fish, the greater the (multiplicative) noise and therefore the likelihood of alignment. Such rare empirical evidence tightly constrains the possible underlying interactions that govern fish alignment, suggesting that E. suratensis either spontaneously change their direction or copy the direction of other fish, without any local averaging (the otherwise canonical mechanism of collective alignment). The work highlights the importance of stochasticity in behavioural inference: rather than simply obscuring otherwise deterministic dynamics, noise can be fundamental to the characterisation of emergent collective behaviours.

Introducing SciProfiles, an Academic Social Network
MDPI is pleased to announce the release of SciProfiles, its social network platform for researchers and scholars.
The purpose of SciProfiles is aligned with MDPI’s broad mission to accelerate discovery and innovation by facilitating immediate access to research results and to serve scholars and communities by providing opportunities for academic networking.
SciProfiles also ambitions to serve as a sustainable, transparent and community-driven research evaluation system aligned with the DORA principles (https://sfdora.org/). Through their scientific profiles, academics can highlight their contribution to research communities, and measure their impact on their field, beyond publication numbers and impact factors. SciProfiles is currently a beta version and will enrich to give researchers the possibility to highlight all of their contributions to science and their scientific communities as authors, reviewers, editors, conference organizers, conference panelists, conference keynote speakers, or even as lecturers or student mentors at their University.
The classic components of popular community social networks, including follower/following, classical metrics, endorsements and recommendations (https://www.mdpi.com/about/announcements/1690), comments (https://www.mdpi.com/about/announcements/1397) are or will be very soon highlighted in SciProfiles as open science contributions.
To help increase the impact and visibility of articles and their authors to an appropriate audience, the platform offers a NewsFeed that includes recommendations of relevant content based on interests, publication history, saved searches or colleagues’ recommendations.
SciProfiles’ avatars are now being integrated on several MDPI platforms, meaning that you will directly access researchers’ profiles from any of the MDPI platforms:
MDPI's journal publishing website: www.mdpi.com
MDPI's conference hosting and management website: www.sciforum.net
MDPI's pre-print website : www.preprints.org
MDPI's knowledge sharing website : www.encyclopedia.pub
MDPI's books store: www.mdpi.com/books

MDPI Now Gives Scholars the Possibility to Endorse and Recommend Articles
MDPI is pleased to announce the release of a new functionality giving the possibility for researchers and scholars to endorse, and formally recommend articles to their colleagues.
MDPI was an early signatory of the San Francisco Declaration on Research Assessment (https://sfdora.org/read/) which calls for improvement in how quality and impact of scholarly research outputs are evaluated, especially in moving beyond journal-based citation metrics (journal Impact Factor, Scopus Citescore, etc.).
MDPI supports the establishment of article-level impact metrics, including citations, views, downloads, and Altmetric scores. These measures serve as an impact indicator for research articles on a case–by-case basis, assessing paper on its own merit. However, these metrics are also subjective and can give a biased picture of the article impact: they do not directly reflect the quality or the intrinsic scientific value of the article.
In our view, community engagement with publications based on community-driven metrics can help to overcome this limitation. We have therefore launched an option for scholars to endorse articles, indicating their own assessment of its content and making a recommendation to their community. This follows our implementation of the open source Hypothesis commenting tool, which has been available for all articles published by MDPI for over a year (https://www.mdpi.com/about/announcements/1397). Both endorsement and commenting are available for all previously published and forthcoming MDPI articles.
In addition to potentially serving as a sustainable solution to article assessment, endorsements will help scientific communities to identify the most relevant articles, independently of the journal in which it was published.
The code for the endorsing functionality, which relies on DOIs and ORCIDs, will be made available on GitHub with an open source license.

Entropy Best Poster Awards at the 39th Workshop on Bayesian Methods and Maximum Entropy Methods in Science and Engineering (MaxEnt 2019)
We are pleased to announce the winners of the two poster awards sponsored by Entropy at the 39th Workshop on Bayesian Methods and Maximum Entropy Methods in Science and Engineering (MaxEnt 2019) held in Garching/Munich (Germany) on 30 June to 5 July 2019.
1st prize (300 CHF, certificate)
"Nested Sampling for Atomic Physics Data: The Nested_Fit Program" by Martino Trassinelli
Nested_fit is a general-purpose data analysis code [1] written in Fortran and Python. It is based on the nested sampling algorithm with the implementation of the lawn mower robot method for finding new live points. The program has been especially designed for the analysis of atomic spectra where different numbers of peaks and line shapes have to be determined. For a given dataset and chosen model, the program provides the Bayesian evidence method for the comparison of different hypotheses/models and the different parameter probability distributions. To give a concrete illustration of applications, we consider a spectrum of examples: i) determination of the potential presence of non-resolved satellite peaks in a high-resolution X-ray spectrum of pionic atoms [2] and in a photoemission spectrum of gold nanodots [3], ii) the analysis of very low-statistics spectra in a high-resolution X-ray spectrum of He-like uranium (see figure) [1] and in a photoemission spectrum of carbon nanodots [4]. In cases where the number of components cannot be clearly identified, as for the He-like U case, we show how the main component position can nevertheless be determined from the probability distributions relative to the single models.

“A Sequential Marginal Likelihood Approximation Using Stochastic Gradients” by Scott Cameron
Existing algorithms such as nested sampling and annealed importance sampling are able to produce accurate estimates of the marginal likelihood of a model, but tend to scale poorly to large datasets. This is because these algorithms need to recalculate the log-likelihood for each iteration by summing over the whole dataset. Efficient scaling to large datasets requires that algorithms only visit small subsets (mini-batches) of data on each iteration. To this end, we estimated the marginal likelihood via a sequential decomposition into a product of predictive distributions $p(y_n|y_{<n})$. Predictive distributions could be approximated efficiently through Bayesian updating using stochastic gradient Hamiltonian Monte Carlo, which approximates likelihood gradients using mini-batches. Since each datapoint typically contains little information compared to the whole dataset, the convergence to each successive posterior only requires a short burn-in phase. This approach can be viewed as a special case of sequential Monte Carlo (SMC) with a single particle, but it differs from typical SMC methods in that it uses stochastic gradients. We illustrate how this approach scales favorably to large datasets using some simple models.

Entropy Best Presentation Award at CNS*2019 Workshop on Methods of Information Theory in Computational Neuroscience
We are pleased to announce the winner of the best presentation award that Entropy sponsored at the CNS*2019 Workshop on Methods of Information Theory in Computational Neuroscience in Barcelona, Spain, on 16–17 July 2019.
“Adaptability and Efficiency in Neural Coding” by Wiktor Mlynarski and Ann Hermundstad
The ability to dynamically adapt to changes in the environment is one of the defining features of sensory systems. In this work, together with my collaborator Ann Hermundstad of Janelia Research Campus, we developed a normative framework to analyze information processing in adaptive sensory systems. We showed that sensory codes optimized for performing task-relevant computations can be different from codes optimized for adapting to changes in the stimulus distributions that underlie these computations. These differences manifest in the speed of adaptation, the accuracy of the code during periods of adaptation, and the accuracy in the adapted state. Our results provide a unifying perspective on adaptation across a range of sensory systems, environments, and sensory tasks.

“Signature of the Transition to a Bound State in Thermoelectric Quantum Transport” by É. Jussiau, M. Hasegawa, and R.S. Whitney
We are studying a quantum dot coupled to two semiconducting reservoirs when the dot level and the electrochemical potential are both close to a band edge in the reservoirs. We have modelled this with an exactly solvable Hamiltonian without interactions (the Fano–Anderson model). The model is known to show an abrupt transition for a broad class of band structures as the dot–reservoir coupling is increased into the strong-coupling regime. This transition involves an infinite-lifetime bound state appearing in the band gap. We determined a signature of this transition in the continuum states of the model, visible as a discontinuous behavior of the dot’s transmission function. This can result in steady-state DC electric and thermoelectric responses having a very strong dependence on coupling close to critical coupling. We show examples where the electrical and thermal conductances and the thermoelectric power factor exhibit huge peaks at critical coupling, while the thermoelectric figure of merit grows as the coupling approaches the critical coupling, with a small dip when reaching it.

"Local Observer-Independent Facts is a weaker assumption than Local Causality" by Anibal Utreras-Alarcon
We study the set of correlations that satisfy the assumptions of freedom of choice, locality (defined as parameter independence) and observer-independent facts. The set of these assumptions was previously shown to be in contradiction with the prediction of quantum theory by Caslav Brukner (Brukner, Entropy 20, 350 (2018)). We found that these correlations are not only different from quantum correlations, but also from those that are characterized by a local hidden-variables model. Indeed, the set of local observer-independent facts correlations is a superset of the set of the local hidden-variables model.
2nd prize (150 CHF, certificate)
"Using the Quantum Zeno Effect to Create Phase Contrast in Electron Microscopy" by Pieter Kruit
The concept of interaction-free measurements as proposed by Elitzur and Vaidman [1] for photons, should also work with electrons [2]. When built into a transmission electron microscope [3], this may lead to imaging modes with reduced damage. In our scheme, the electron wave is split by an amplitude splitter in a large component (the reference beam) that passes through a hole in the specimen and a small component (the sample beam) that passes through the sample. After the passage, both beams are cycled back to the amplitude splitter and the process is repeated. If the sample has no effect on the beam, the amplitude in the sample beam slowly builds up until it has the full intensity after m cycles. If the sample does have an influence, either on the amplitude or on the phase, the intensity transfer is disturbed by the quantum Zeno effect, and the intensity stays in the reference beam. Using the model explained in [4], the signals in the reference beam (R) and the sample beam (S) can be calculated as a function of the phase change in the specimen. To get an impression of what kind of images our method would produce, we simulate electron microscopy images of proteins and show “iso-phase lines” or “iso-phase areas” while only causing damage around these lines or in these areas.

Popularity of Preprints Continues to Grow
2018 was a great year for preprints, with increasing numbers of authors looking to make their papers available online before peer review. Along with other preprint servers, our platform Preprints.org saw an increase in the uptake from authors, and more than double the number of announced papers compared to 2017. In fact, we recently passed two important milestones: 8000 preprints online and 30,000 authors.
We believe that the whole research community has the opportunity to benefit from work being available online as early as possible. We thank and congratulate our authors for supporting us to make this goal a reality.
In 2019, we will be looking carefully at how to provide better value for authors, maintain efficiency while growing in size, and make sure we remain well-connected with the research community.
If you want to participate, you can consider screening preprints or joining our advisory board. And, of course, posting your own work.

MDPI Welcomes Plan S
Recently, it was announced that a group of European funders supported 10 principles that will help to expand open access, known as Plan S. MDPI warmly welcomes this move as a step towards achieving more open and accessible communication of research across all disciplines. Some aspects remain to be clarified, however the details given so far match the aims and values that MDPI has held over the past two decades.
We believe that open access publishers should be active participants in discussions around Plan S, particularly regarding potential new business models and practical aspects of implementation. MDPI supports APCs as a transparent unit of payment for article publishing, however we are committed to exploring other measures and recently signed the Jussieu Call. Sustainability is a key value for MDPI, and future funding models should have at their heart the sustainability of knowledge and research dissemination. Plan S provides an opportunity for funders and publishers to directly discuss funding of open access journals in ways that are beneficial to all parties involved.

Winner of the Entropy Best Paper Award at MaxEnt 2018—Sascha Ranftl
The editorial team of Entropy is happy to announce the winner of the Best Paper Award at the Max Ent 2018 conference, held in British Library, London, UK on 2–6 July 2018. The most outstanding paper was selected by an evaluation committee chaired by Prof. Emma McCoy.
The Editor-in-Chief of Entropy, Prof. Dr. Kevin H. Knuth (University at Albany, NY, USA), granted the certificate to the winner Mr. Sascha Ranftl (Graz University of Technology, Austria), whose work was titled “Bayesian Analysis of Femtosecond Pump-Probe Photoelectron-Photoion Coincidence Spectra”.
The awarded paper sheds light on the statistics of coincidence measurements, where a single electron is assigned to a single ion, both originating from the same ionization event. In combination with ultrafast lasers, this technique allows to understand the dynamics of molecules in the regime of femtoseconds. By employing Bayesian probability theory to deal with false coincidences, which an experimentalist cannot distinguish from true coincidences, the authors find significant impact on the analysis of the experimental data, and the interpretation of the underlying physical processes therefore.
Sascha Ranftl recently completed his Master’s Thesis, in the role of an experimentalist, in the femtosecond laser lab under the supervision of Prof. Markus Koch (Institute of Experimental Physics) and now enrolled in a PhD at the Institute of Theoretical and Computational Physics under the supervision of Prof. Wolfgang von der Linden. His current research interest concerns applications of Bayesian inference in the field of biomedical engineering, particularly computational biomechanics and the modelling and simulation of the life-threatening disease “aortic dissection”.

Congratulations to Entropy for Publishing the 20th Volume in 2018
We would like to send warm wishes from the Editor-in-Chief of Entropy and look to the future. Acknowledgement of our past achievements provides the strongest stimulus for future endeavor.
As the journal Entropy enters its 20th year, one cannot help but reflect not only on how far the journal has come, but also on how far the field has come. I have been Editor-in-Chief of Entropy for the past six years, which is roughly one-third of the lifetime of the journal. While my predecessors did an excellent job in establishing the journal, I am grateful to have had the opportunity to help it grow. On my arrival in 2012, Entropy had an impact factor of 1.183. This last year, 2017, the impact factor reached a respectable 1.821 and it promises to break 2.0 in the next year or so, as Entropy continues its rapid growth.
I have been an active member of the MaxEnt (Bayesian Inference and Maximum Entropy Methods in Science and Engineering) community since I first attended the MaxEnt 1997 workshop over twenty years ago, just before the birth of the journal Entropy. My MaxEnt colleagues had long been concerned about the fact that there were few precious journals that would entertain their research papers for publication. Historically, the MaxEnt community has been known for being about a decade or so ahead of its time. While this is an exciting position to be in, it is extremely difficult from a pragmatic perspective, since it is common for the scientific community to undervalue or, worse, to misunderstand our work. We continue to encounter some of these difficulties at Entropy, since it is still frequent for the scientific community to think of entropy as a thermodynamic quantity rather than a tool for making inferences. Fortunately, as the journal continues to grow, the number of those who understand entropy grows.
I was delighted to take the helm of Entropy in 2012. I had access to a large circle of excellent scientists who had much to contribute and could profit from a growing journal with a scope to accommodate their work! Contribute they did. But I was astonished to discover so many other people out there who were applying entropic concepts to their problems. I was, and still am, excited to learn of new applications and advances and I am grateful that Entropy is in an excellent and respected position to present and showcase them.
— Prof. Dr. Kevin Knuth
Editor-in-Chief of Entropy

MDPI has signed the Jussieu Call for Open Science and Bibliodiversity
The Jussieu Call aims to develop and implement alternative models to meet the aims of open science while promoting bibliodiversity. In particular it wishes to promote new business models for funding open access publication. It was drafted on the Jussieu campus in Paris by a group of French researchers and scientific publishing professionals.
MDPI supports scholarly communities and initiatives that innovate and further promote Open Access publishing. There is a need to explore different frameworks to fund open access in ways that ensure that excessive funds are not diverted from research towards publishing. Many fair funding models already exist, and they can be further developed and extended. These include institutional support, library contributions or subsidies, premium services, participatory funding, etc. For this reason, MDPI has signed up to the Jussieu call and welcomes its aims.

Credit for Preprints Comments via Publons
Preprints.org is a platform run by MDPI that allows authors to make early versions of manuscripts available before peer review has been completed.
One of the major benefits of putting a preprint online is to get feedback before journal submission. Until now, however, the feedback has been on a voluntary basis. Preprints is delighted to be the first preprint server to collaborate with Publons to acknowledge substantial comments as reviews and give commentators the opportunity to receive credit for their efforts.
When you add a comment to any article, there is a check box to click for it to appear on Publons. If you have already linked your account it will be passed on automatically. If you don't already have a Publons account, you will be contacted soon afterwards with instructions on how to create one.
We appreciate the enthusiasm and cooperation of Publons in this project and expect it to be of great benefit to authors and commenters alike.

The 6th World Sustainability Forum: Final Press Release
Basel, 29 January 2017
The 6th World Sustainability Forum #WSF2017SA: African universities critical to achieving the Sustainable Development Goals
Jeffrey and Sonia Sachs win first World Sustainability Award.
Universities need to take the lead in solving the greatest challenges the world faces today, particularly in Africa. They need to do this not only through education – teaching the next generation to think critically and creatively to find sustainable solutions – but also through research that cuts across a range of disciplines. To ensure these solutions are implemented, they need to partner with the private sector and with government.
This was the key message from the 6th World Sustainability Forum (WSF2017), which took place in Cape Town on 27 and 28 January 2017. Sponsored by MDPI and the journal Sustainability under the patronage of the Universities of the Western Cape (UWC), Cape Town (UCT), University of Basel and the National Research Foundation (NRF) of South Africa, the conference was attended by key national and international speakers, including world-leading economist Professor Jeffrey D. Sachs, senior United Nations (UN) advisor and director of the Earth Institute at Columbia University.
The WSF is an annual sustainability conference which addresses research in a range of areas related to sustainable development and sustainability globally. This was the first WSF to take place on the African continent. Discussions at the 2017 conference were driven by the 17 sustainable development goals (SDGs) adopted as part of the 2030 Agenda for Sustainable Development by the UN in September 2015.
Achieving the SDGs “is the moonshot for our generation,” said Sachs. “Like the moonshot [moon landing] of the 1960s, these are tough, bold and achievable objectives.”
“This is a nasty, tough world we live in, and our world agrees on very little. So when 193 governments agree on something, that is important. And when they agree on something as important as sustainable development, that is really something for us to grab hold of – that is a lifeline.”
There was agreement at the WSF that the SDGs are particularly important for Africa, and that African universities in particular have a role to play in achieving them.
Said Professor Tyrone Pretorius, vice-chancellor of UWC: “The quest for sustainable development can only be met through education. Universities today are the oil that fuels the knowledge economy.”
As part of the drive to develop academic capacity to provide the knowledge needed to meet the SDGs, WSF2017 was preceded by the 1st Postgraduate Forum on Sustainability. “A series of workshops for postgraduate education linked to WSF are important, in order to equip postgraduates with the skills necessary to promote sustainability,” said Professor Thandi Mgwebi, director for research at UWC. A second postgraduate forum will take place alongside the WSF2018 in Beijing.
This capacity development is particularly critical to Africa. Said Sachs: “African universities need to do research to find solutions to Africa’s development challenges, because no other university will.”
The UN set a target of achieving the SDGs by 2030: “I regard this as the breakthrough period to end extreme poverty on the continent,” said Sachs, “and for Africa to become one of the most dynamic centres of the world economy.”
It is a critical time for South African universities, said Professor Mamokgethi Phakeng, deputy vice-chancellor for research and internationalisation at UCT: “Higher education is at a crossroads, and there is much polarisation. We need to think carefully about how this sustainable development agenda is owned by all so that it is inclusionary.”
There was also strong emphasis on public–private partnerships – for universities, business and government to work together to achieve the goals.
Said Professor Francis Petersen, deputy vice-chancellor at UCT and vice-chancellor designate at the University of the Free State: “Business sustainability has become critical, because there is increasing demand and complexity of demand on business from the natural, social and economic environment. Sustainability cannot be a standalone issue, divorced from business as usual. Sustainability needs to be embedded into business.”
Environmental crises and climate change was also high on the WSF agenda. In his keynote address, Sachs noted the irreversibility of the climate- and environmental-related challenges.
“If we don’t get our act together, we lose the chance of safety,” he said.
Said Professor Mark New, pro vice-chancellor and director of the African Climate and Development Initiative at UCT: “We have a fundamental challenge in responding to climate change, and we must go further than just putting a plaster on a wound. We need to address the deep structural issues, to move from our current model of development into climate-compatible development.”
“This requires researchers to find the evidence for the correct development pathways to take, and then support the ability of policymakers at all levels to enable the shift to climate-compatible development planning.”
Said Dr. Aldo Stroebel, executive director of international relations and cooperation at the NRF, in closing: “We have seen over the past two days an urgency towards the next step of thinking, that critical type of framework that we all must engage with, not only from an academic perspective, but further up into the policy environment and into rural-based environments where one can clearly see the links and effectiveness of the work.”
World Sustainability Awards
The first World Sustainability Award and the first Emerging Sustainability Leader Awards were presented by Prof. Thandi Mgwebi, Director of Research at UWC, and Dr. Franck Vazquez, CEO of MDPI, during the ceremony on 27 January 2017 as part of the gala dinner of the 6th World Sustainability Forum in South Africa.after day one of proceedings of the 2017 World Sustainability Forum South Africa.

Cape Town to Host the 6th World Sustainability Forum
Cape Town will host the 6th World Sustainability Forum at the Cape Sun Hotel on 27 and 28 January 2017. This prominent event, held for the first time in Africa, will include many illustrious South African and international experts, such as Her Excellency Graça Machel (Sustainable Development Advocate for the United Nations, Mozambique), Joyene Isaacs (HoD Agriculture Western Cape Government), Jeffrey Sachs (Columbia University, USA), Max Bergman (SRaM, University of Basel), Mark New (Pro Vice-Chancellor, University of Cape Town), Frans Swanepoel (FutureAfrica, University of Pretoria) and Francis Petersen (Vice-Chancellor-designate, University of the Free State). The Forum will provide a stage for national and international debates on sustainability in South Africa, the African continent, and about international perspectives on sustainability. It brings together researchers and representatives from government and the business sector to discuss a wide-ranging set of issues associated with sustainability, including food security, water and energy scarcity, mining, poverty reduction, climate change, and urbanisation.
The next few decades will be marked by profound changes in the relationships between global economics, national societies, and the environment. We have entered what some call the Anthropocene, an age in which human activity dominates the climate and the environment. These changes will have numerous consequences on societies around the globe. South Africa and Africa will play a central role, for better or worse, in creating opportunities and risks during these changing times as Africa is profoundly influencing and being influenced by global developments.
The adoption of the 17 United Nations Sustainable Development Goals and the 2030 Agenda for Sustainable Development in September 2015 was accompanied by what insiders considered an optimism they have not experienced in relation to UN resolutions before. The relative efficiency in the drafting, the lack of trenches between East and West, or between North and South, and the unanimity of support of the 193 countries speak volumes. In stark contrast, sustainability seems to go against a changing economic and political tide, where waves of nationalism and protectionism from some of the most powerful countries risk the wellbeing of the rest of the world. The 6th World Sustainability Forum will enable fruitful exchanges, which sensitise South African and international communities to the global urgency and specifics of sustainability.
The Forum will showcase the work of internationally renowned researchers and include more than 150 presentations. During the conference dinner, the World Sustainability Award, associated with a US$ 100 000 prize, will be announced, as well as the Emerging Sustainability Leader Award, associated with a US$ 10 000 prize. The prizes are sponsored by the MDPI Sustainability Foundation and Sustainability, an academic open access journal by MDPI. The World Sustainability Forum is preceded by the Postgraduate Forum on Sustainability, which will introduce more than 100 young scholars from South Africa and the African continent to sustainability research. Both events are organized and sponsored by the University of Cape Town, the University of the Western Cape, the University of Basel, MDPI, and by the National Research Foundation of South Africa.
